Steam at a pressure of 15 bar and a temperature of 320°C is contained in a large vessel shown below. Connected to the vessel through a valve is a turbine followed by a small initially evacuated tank with a volume of 0.6 m³. When power is required, the valve is opened and the tank fills with steam until the pressure is 15 bar. The temperature in the tank is then 400°C. The filling process takes place adiabatically and kinetic and 3 potential energy effects are negligible. The amount of work developed by the turbine is kJ. Vessel valve Turbine valye 70 X At 15 bar and 320°C: Enthalpy of steam = 3081.9 kJ/kg At 15 bar and 400°C: = Initially evacuated tank Internal energy of steam 2951.3 kJ/kg, 3 specific volume of steam = 0.2027 m²/kg) Steam at a pressure of 15 bar and a temperature of 320°C is contained in a large vessel shown below.
