The flash cooling process of a milk pasteurization vat uses refrigerant R-134a. The cycle is illustrated in the Log P-H diagram below. The throttling process between states 3 and 4 is perfect. The evaporator operates at T1 = 4ºC and the compressor discharges T2 = 60ºC and a with a condensation pressure P2 = 1.2 MPa.

Please explain how you get the values.

What is the value of h1 in kJ/kg?

What is the value of h2 in kJ/kg?

What is the value of h3 in kJ/kg?

What is the value of h4 in kJ/kg?

What is the value of vapor quality x at 4?

The compressor for the Vat flash cooler is in steady state, the gain in kinetic energy of the refrigerant across the compressor is negligible, the compressor does boundary work on the refrigerant to the tune of w = 55.26 KJ/kg, what is the specific heat transfer (q) at the compressor?

The flash cooling process of a milk pasteurization vat uses refrigerant $\mathrm{R}?134\mathrm{a}$. The cycle is illustrated in the Log P-H diagram below. The throttling process between states 3 and 4 is perfect. The evaporator operates at $\mathrm{T}1=4^{?}\mathrm{C}$ and the compressor discharges $\mathrm{T}2=60^{?}\mathrm{C}$ and a with a condensation pressure P2 = 1.2 $\mathrm{MPa}$.
