An ideal vapor compression refrigeration cycle with R134a as the
working fluid operates between the pressure limits of 200 kPa and
1200 kPa. Determine
a) the mass fraction of the refrigerant that is in the liquid phase
at the inlet of the evaporator, and
b) the amount of heat transfer (in kJ/kg) to the refrigerant in
the evaporator (??).
