Aclosed, rigid, 0.45 m^3 tank is filled with 12 kg of water. the initial pressure is p1 = 20 bar. the water is cooled until the pressure is p2 = 4 bar. determine the initial quality, x1, and the heat transfer, in kj.

initial quality = 0.3690

heat transfer = 979.63 kJ/kg

Explanation:

Given data:

volume of tank 0.45^3

weight of water 12 kg

Initial pressure 20 bar

final pressure 4 bar

Specific volume

At Pressure = 20 bar, from saturated water table

inital quality is x =0.3690

Heat transfer is calculated as

from saturated water table, for pressure 20 bar ,

     =908.79 + 0.0357(1890.7)

      = 979.63 kJ/kg
