Question
An Aircraft air conditioning system comprises of a reciprocating compressor and during thecompression process a refrigerant gas is compressed. The cylinder is initially at a volume of 0.05m3 and contains 0.1 kg of ammonia at a pressure of 3 bar.The gas is subjected to a reversible adiabatic compression process to a final volume of 0.01 m3.Assuming the ammonia to be a perfect gas, calculate:Its initial temperature, pressure at the end of the compression stroke and the work done incompressing the ammonia.For ammonia: R = 530 J/kgK and cv = 166 J/kgK
