5. (a)Consider adiabatic compression of 2 kg of air in a piston-cylinder assembly from 1 bar and 330 K (State 1) to 14 bar and 700 K (State 2). Air can be considered an ideal gas at these conditions and molecular weight of air is 28.97 kg/kmol. Find the entropy of air in State 1 and State 2. Using the entropy balance equation for a closed system calculate the entropy generation (kJ/K) during the compression process. (b) If entropy decreases...
5. Determine the change in the entropy of air, in kJ/kg-K, as it undergoes a change of state from 100 kPa and 20 C to 600 kPa and 300C using the equation of state P(V-a) -RT where a 0.01 m/kg, and compare the result to the value obtained by using the ideal gas equation of state.
