In the vapour compression cycle shown in the figure the evaporating and condensing temperatures are 260 K and 310 K, respectively. The compressor takes in liquid vapour mixture (state 1) and isentropically condition (state 2). The specific heat of the liquid refrigerant is 4.8 kJ/kg-K and may be treated as constant. The enthalpy of evaporation for the refrigerant at 310 K is 1054 kJ/kg.
The difference between the enthalpies at state points 1 and 0 (in kJ/kg) is __________
