Concentric Tube Heat Exchanger (Product Code: SLE/EA/16) is a tube-in-tube heat exchanger used to show how heat passes from a hot fluid in one tube to a cold fluid in the other in college engineering laboratories. The simplest of the optional heat exchangers, it is built in two equal halves joined by intermediate pipes, giving two extra measurement points at the midpoint. This lab equipment for technical institutes is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Concentric Tube Heat Exchanger Used For?

With readings at the inlets, the outlets and the two midpoint positions, students can plot how the hot and cold fluid temperatures change along the exchanger rather than seeing only the end values. That clearer temperature profile makes it easier to explain the log mean temperature difference and why the rate of heat transfer falls as the two streams approach each other in temperature.

Because the geometry is so simple, this is where many learners first calculate an overall heat transfer coefficient. Colleges planning engineering lab equipment in India for a heat transfer course can start with this unit and add plate and shell-and-tube types later for comparison.

Unsteady State Heat Transfer (Product Code: SLE/EA/19) is a transient heat transfer apparatus used to measure the temperature changes in solid test shapes suddenly immersed in a temperature-controlled water vessel in engineering laboratories. Its test shapes differ in dimensions and material, so students see how surface area, shape and thermal conductivity alter the rate of heat transfer. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM engineering lab equipment manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Unsteady State Heat Transfer Apparatus Used For?

Many real heating and cooling processes, from quenching a metal part to warming food, never reach a steady state, and this apparatus lets students study that transient behaviour directly. They immerse one test shape, record how its temperature changes with time, then repeat with the other shapes and compare the curves. The exercise goes a step beyond a simple Newton law of cooling apparatus, because shape and material become variables as well.

The results can be checked against lumped-capacitance and transient conduction theory, introducing ideas such as the Biot number. Let the water reach its controlled temperature and start each shape from the same initial condition, so the comparison between shapes stays fair.

OEM Manufacturer

This apparatus is manufactured by Jain Scientific Equipments Private Limited, trading as ScienceLab, which is its OEM (original equipment manufacturer), at the company's own licensed factory in Saha, Ambala, Haryana, India. Departments equipping a thermal lab from scratch can have it quoted alongside other heat transfer apparatus from the same manufacturer. If additional or replacement test shapes are needed later, ask us directly. The ScienceLab company profile has more background.

Pair transient tests with these steady-state and measurement experiments:

• Radial Heat Conduction Experiment — steady radial conduction for contrast with transient results.
• Extended Surface Heat Transfer — conduction along a heated bar with surface heat loss.
• Computerized Thermal Conductivity of Powder — measures the conductivity property that drives transient response.
• Temperature Measurement and Calibration Apparatus — builds confidence in temperature readings.

The full list is in Thermodynamics & Heat Transfer Lab Equipment.

Frequently Asked Questions

What does unsteady state heat transfer mean?
Unsteady state heat transfer means temperatures change with time rather than staying fixed. On the Unsteady State Heat Transfer apparatus, students measure the transient temperature changes in a test shape after it is suddenly immersed in the controlled water.

Why are the test shapes of different sizes and materials?
The test shapes of the Unsteady State Heat Transfer apparatus have different dimensions and materials, giving different heat transfer areas and thermal conductivities. Comparing their results shows how surface area, shape and thermal properties affect heat transfer.

How is the water temperature kept constant?
A controller switches the electric heater of the Unsteady State Heat Transfer apparatus to hold a constant bulk water temperature, and the large water volume means immersing a test shape has a negligible effect on that temperature.

How are temperatures read during a test?
Precision instruments on the Unsteady State Heat Transfer apparatus measure temperatures at key points and show them on clear multi-line displays, so students can follow the transient changes as they happen after immersion.

Who manufactures the Unsteady State Heat Transfer apparatus?
The Unsteady State Heat Transfer apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own licensed factory at Saha, Ambala, India, and is supplied factory-direct to institutions, dealers and importers.

Students set the hot water flow on the needle valve and the air flow on the slide valve, read the air flow from the orifice plate pressure difference, and record the inlet and outlet temperatures of both streams. Comparing the heat given up by the water with the heat picked up by the air gives an energy balance, the same principle behind a car radiator or an air-conditioning coil.

Changing the air flow while holding the water conditions steady shows how strongly the air side governs the heat transfer rate. Because its heat output does not greatly warm a reasonable-size room, the unit is practical for polytechnics buying vocational training lab equipment for HVAC and thermal courses.

Saturated Steam The Marcet Boiler (Product Code: SLE/EA/21) is a Marcet boiler apparatus used to show how the pressure of saturated steam rises with its temperature in thermodynamics laboratories. An insulated, electrically heated pressure vessel with a special-purpose glass window lets students watch water boil while a transducer, thermocouple and Bourdon gauge track the changing conditions. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of engineering educational equipments in India, at its own factory in Ambala.

Key Details

What Is the Marcet Boiler Used For?

Students heat the water and record pairs of pressure and temperature readings as both rise, then compare their curve with published steam tables. The exercise makes the idea of saturated conditions concrete and leads naturally to the Clausius-Clapeyron relation. Watching the boiling through the glass window helps learners connect the numbers with what is happening inside the vessel.

Before switching on, check the water level through the window, and never obstruct the high temperature vent pipe that carries steam to the drain. It is a natural first thermodynamics practical for colleges and lab equipments for technical institutes.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of this Marcet boiler and produces it at its own licensed factory at Saha, Ambala, Haryana, India. Because the boiler is a pressure vessel, buyers want to know who stands behind it; here it is the manufacturer itself, so questions on the relief valve, thermostat or gauge come straight to us.

Expansion Of Perfect Gas (Product Code: SLE/EA/22) is a thermodynamics apparatus used to study how air behaves as a perfect gas when it moves between a pressurised vessel and an evacuated vessel in engineering laboratories. Two transparent, rigid, interconnected vessels are charged by an electrical air pump, and the important readings are captured, displayed and charted on a computer in real time. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM technical educational equipment manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Perfect Gas Expansion Apparatus Used For?

Students pressurise one vessel, evacuate the other and then open the valves between them, watching the readings respond as gas expands from one vessel into the other. The results are compared with perfect gas relationships such as Boyle's law. Using a single vessel gives simpler exercises, while the pair together opens up a wider set of thermodynamic processes.

Because readings are charted on a computer in real time, fast pressure changes that are hard to note by hand are captured cleanly for later calculation. Close the valves correctly before running the pump, and protect the transparent vessels from knocks. It is a modern option for colleges sourcing engineering lab equipment in India with computer-based data.

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM (original equipment manufacturer) of the Expansion Of Perfect Gas apparatus, which it manufactures at its own licensed factory in Saha, Ambala, Haryana, India. Questions about the data capture arrangement, the air pump or the valves are answered by the manufacturer rather than a reseller — just ask us.

View the whole Thermodynamics & Heat Transfer Lab Equipment range.

Frequently Asked Questions

What does the Expansion Of Perfect Gas apparatus consist of?
The Expansion Of Perfect Gas apparatus consists of two frame-mounted, interconnected, transparent and rigid vessels — one for pressure and one for vacuum — with an electrical air pump, valves and tappings, and computer-based data capture.

Can the two vessels be used separately?
Yes. The vessels of the Expansion Of Perfect Gas apparatus are independent, so each can be used on its own, and they can also be used together to enable the study of various thermodynamic processes involving expansion between them.

How are the vessels pressurised and evacuated?
The Expansion Of Perfect Gas apparatus uses an electrical air pump together with valves and tappings to pressurise one vessel and draw a vacuum in the other, so no separate compressor is described for the basic set-up.

Does the apparatus need a computer?
The Expansion Of Perfect Gas apparatus provides real-time data capture, monitoring, display, calculation and charting of readings on a computer. Ask us through the contact page what computer arrangement is included in your quotation.

Which courses use this apparatus?
The Expansion Of Perfect Gas apparatus suits applied thermodynamics courses in mechanical, chemical and aeronautical engineering, where students must connect the perfect gas laws with measured pressure behaviour in real vessels.

Conductivity Of Liquid And Gases (Product Code: SLE/EA/23) is a thermal conductivity apparatus used to measure how well a liquid or gas conducts heat across a thin layer between a heater and a water-cooled heat sink in engineering laboratories. Three concentric cylinders hold the electric heater, the test fluid and the cooling water, with thermocouples on both edges of the fluid layer. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and scientific instruments manufacturer in India, at its own factory in Ambala.

Key Details

What Is the Liquid and Gas Thermal Conductivity Apparatus Used For?

Students fill the thin annular gap with the chosen fluid, start the cooling water and heater, and wait for the thermocouple readings to settle. From the heat input and the temperature difference across the layer, they calculate the fluid's thermal conductivity using the equation for radial conduction through a cylindrical shell. The printed schematic on the base plate helps them identify each measuring point quickly.

Keeping the fluid layer thin limits convection, so heat crosses it mainly by conduction. Repeating the test with different fluids shows clearly why gases are far poorer conductors than liquids, a useful result for heat transfer and fluid-property courses using engineering lab equipment in India.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of this conductivity apparatus and manufactures it at its own licensed factory in Saha, Ambala, Haryana, India. Buying from the maker means one contact for set-up questions, replacement thermocouples or additional units for new benches — ask us for any of these. The company supplies engineering colleges, dealers and importers directly; its background is on the ScienceLab profile.

• Extended Surface Heat Transfer — conduction along a heated bar.

Explore more in Thermodynamics & Heat Transfer Lab Equipment.

Frequently Asked Questions

How does the Conductivity Of Liquid And Gases apparatus work?
The Conductivity Of Liquid And Gases apparatus uses three concentric cylinders: an inner electric heater, a thin layer of test liquid or gas, and an outer water-cooled heat sink. Heat conducts from the heater through the fluid layer to the sink.

Can it test both liquids and gases?
Yes. In the Conductivity Of Liquid And Gases apparatus, either a test liquid or a test gas forms the thin second cylinder around the heat source, so students can compare the conductivity of different fluids on the same apparatus.

Where are temperatures measured?
Thermocouples on the Conductivity Of Liquid And Gases apparatus measure the temperature at the inside and outside edges of the cylinder of test liquid or gas, giving the temperature difference needed to calculate its thermal conductivity.

Why is the test fluid layer thin?
The test fluid in the Conductivity Of Liquid And Gases apparatus forms a thin cylinder so that convection currents have little room to develop, which means the heat crossing the layer travels mainly by conduction, as the calculation assumes.

What else is needed to run the apparatus?
The Conductivity Of Liquid And Gases apparatus uses cooling water for its outer cylinder, plus a supply for the heater and a readout for the thermocouples. Ask us via the contact page which unit is quoted to provide these.

Who manufactures the Conductivity Of Liquid And Gases apparatus?
The Conductivity Of Liquid And Gases apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, India, and is supplied directly to institutions and trade buyers.
