Cross Flow Heat Exchanger (Water-to-Air)
The apparatus is for studying heat transfer from hot water to cross flow air such as in automobile radiator.
The unit consists of an air duct with outlet damper, an automotive radiator, an axial flow fan and a service module. The module provided hot water with transfer pump and control and measuring instruments.
TYPICAL EXPERIMENTS:
- Determination of heat transfer from hot water to air by finned tubes
- Determination of heat transfer coefficient
- Effect of flow rate and temperature difference

Air Flow and ThermodynamicsTwo Stage Air Compressor Test Set: Air-Water Cooled
The test set is for studying the two stage reciprocating air compressor characteristics.
For educational purpose, the two stages are separated and can be operated at different speeds. Both stages are connected by vee-belts to the same motor with an advanced inverter. The second stage compressor has three alternative pulleys to vary the pressure ratio between the two stages. An intercooler is provided between first and second stage. The air receiver has a drain valve, safety valve, pressure switches and a discharge valve. The piping system is arranged such that intercooler or second stage compressor can be by passed. The unit is equipped with necessary measuring instruments and is on wheels.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Compressor characteristics e.g. volumetric efficiency, isothermal efficiency, pressure ratio, temperature ratio.
- Effect of compressor speed.
- Effect of intercooler.
- Effect of second stage drive ratio.
- Effect of inter cooling.
- Air water heat exchanger demonstration.
TECHNICAL DATACompressors: – Type Air-cooled, two stage – Displacement 300 ml. or approximate equal – Second stage Single cylinder, completed with three different diameter pulleys – Maximum working pressure 12 kg/cm2 Air receiver Approx. 90 L or as requested Intercooler Water cooled, counter flow heat exchanger Measuring instruments – Pressures Pressure gauges at first stage and second stage outlets, and air receiver – Air flow rate Inlet orifice plate with air box and inclined water manometer, 0-450 mm x 1 mm
