An adiabatic compressor takes air (assumed as ideal gas) flowing at a rate of 0.3 kg/s from 100 kPa and 22 C to 800 kPa. Assuming constant values of cp 1.020 kj/kg K, cv = 0.733 kJ/kg K, k = 1.391, and neglecting the changes in kinetic and potential energies, determine (a) The exit temperature if the process is reversible, T2s (K), (b) the exit temperature if the compressor has an isentropic efficiency of 80%, T2 (K) (c) the power input required to drive the compressor with the isentropic efficiency of 80%, W_in (kW). (d) cp, cv and k change with temperature. What is the assumed temperature (K) at which cp =1.020 kl/kg K, cv = 0.733 kl/kg K, k = 1.391? Write correct numerical answers to 3 significant figures.
