value of y is _____4_______.

Consider an ideal vapor-compression refrigeration cycle using Freon 410A (see . https://www.freon.com/en-/media/files/freon/freon-410a-si-thermodynamic-properties.pdf) The pressure in the evaporator is 10y kPa (That is, if y = 3 the evaporator pressure is 30 kPa). and the temperature at the exit of the condenser is 40oC. The mass flow in the system is (0.05 + y/200) kg/s.   (That is, if y =3, then the mass flow is 0.0.065 kg/s).

  1. Find the enthalpy at the entrance to the compressor.                    h = __________ kJ/kg (+ 3 kJ/kg)

  1. Find the enthalpy at the exit of the compressor.                              h = __________ kJ/kg (+ 5kJ/kg)

  1. Find the enthalpy at the exit of the condenser.                                h = __________ kJ/kg (+ 3kJ/kg)
