1. A wet-steam drum with a total volume of 2m3 and a pressure of 200kPa is 20% water and 80% water vapor. Accordingly, the water vapor in the drum; a) its temperature, b) Its total mass, c) degree of dryness, d) its specific volume, and e) Calculate its enthalpy 2. An insulated tank contains 5kg of water in the saturated liquid-vapour phase at 100kPa, with 75% of the total mass being liquid. The water in the tank is heated by means of an electric heater with a voltage of 110V and a current of 8A, until it completely passes into the vapor phase. Calculate the duration of the applied heating process
