Question:

A 0.5 m3 tank initially contains saturated liquid water at 200oC. A valve on the bottom of the tank is opened and half the liquid is drained. Heat is transferred from a source at 300oC to maintain constant temperature inside the tank. Determine (a) the heat transfer (Q) and (b) the reversible work. Assume the surroundings to be at 25oC and 100 kPa.
