Process of Ideal gasses 35m3 /min of air flows steadily through a compressor. It undergoes an isentropic change from 320C and 0.85 bar to 1.7 bar. The measured change in kinetic energy is 2.5kJ/kg. Neglect changes in potential energy and determine (a) the change in internal energy; (b) the compressor power requirement. A piston cylinder arrangement containing 2.2 kg of methane at 120kPa is heated at a constant temperature of 2400C. If during the nonflow process the heat transferred in kJ is numerically equal to half the final enthalpy, determine (a) the final pressure and volume; (b) the work
