The test rig comprises of a two-stage air compressor fitted with an air tank with orifice, pressure gauges 9 an energy meter to measure the input & a Temperature indicator measures the temperatures at various points. The compressor is mounted on air receiver along with the motor, and is provided with air relief valve (safety) and a pressure switch. The unit determines volumetric efficiency and isothermal efficiency at various discharge pressures
