A steam boiler of volume 2.3 m3 initially contained 1.7 m3 liquid water in equilibrium with
0.6 m3 of vapour at 100 kPa. The boiler is heated keeping the inlet and discharge valves closed.
The relief valve is set to lift when the pressure in the boiler reaches
5500 kPa. Determine the amount of heat supplied to the contents in the boiler before the relief
valve lifts.
