An air receiver has a capacity of 0.86m³ and contains air at a temperature of 15°C and a pressure of 275 kN/m?. An additional mass of 1.7 kg is pumped into the receiver. It is then left until the temperature becomes 15°C once again. Determine, a) the new pressure of the air in the receiver, and b) the specific enthalpy of the air at 15°C if it is assumed that the specific enthalpy of the air is zero at 0°C. Take Cp = 1.005 kJ/kg, C = 0.715 kJ/kg K
