Question: 020 kg of air at pressure of 113 kpa occupies...

Question details

0.20 kg of air at pressure of 113 kPa occupies 0.18 m3 and from this condition it is compressed to 1237 kPa accordingly to the law P*(V)1.28 = constant. Determine change of internal energy of the air in kJ,

Cp=1.005 kJ/kg K

Cv=0.718kJ/kg K

R=0.287 kJ/kg K
