1 1 Helium is compressed through a compressor steadily. At the inlet the pressure is P₁ = 100kPa and the temperature is T₁=300K. At the exit the pressure is P₂ = 600kPa and the temperature is T=390K. The power input is W=5000kW and the heat loss rate is Q = 1000k//s during 1 2 out this process. Neglect the kinetic and potential energy changes. Assume helium is ideal gas with a constant specific heat c=5.1926 kJ/kg . K and its P specific heat ratio k == 1.667, which means that enthalpy can be calculated using h=c_T. Calculate the enthalpy per unit mass at the P C exit h kJ/kg
