Determine the change in the entropy of air, in kJ/kg?K, as it undergoes a change of state from 100 kPa and 208C to 600 kPa and 3008C using the equation of state P(v 2 a) 5 RT where a 5 0.01 m3 /kg, and compare the result to the value obtained by using the ideal gas equation of state.
ANSWER:Step 1 of 4
The entropy change of air between two specified states is to be compared for two equations of states.
We assume that constant specific heats for air can be used.
For air at the average temperature , (Table A-2b) and (Table A-1).
