Question

(b)
At initial state (state-1), a tank contains water vapor at 250°C with an
unknown pressure. When the tank is cooled isochorically to 150°C at second
state (state-2), the vapor starts condensing. Since the tank is not insulated,
further heat loss occurred isobarically until all the water vapor in the tank
turns to liquid at final state (state-3).
(iv)
Estimate the pressure, specific volume, and the enthalpy at its initial
state;
(v)
Determine the pressure, specific volume, and enthalpy at state-3; and
(vi)
Sketch the process from initial to final state on a T-v diagram complete
with the saturation line. Plot the point and pressure curve for each
state, and show their axis values on the diagram. Describe the phases
of each state in the calculations.
Note: Show all steps and calculations involved.
