. Steam enters a turbine at 300 °C, 2 MPa (state 1). The turbine is connected to a closed, initially empty tank of 50 m³. The turbine operates until the tank pressure reach 2 MPa at which point the final temperature is 250 °C. Consider that steam flows through the turbine at a constant mass flow rate and assume that steam properties are uniform at each instant (state 2 is the same along the line and the tank). If the entire process is adiabatic, what is the work output from the turbine (MJ). Hint. Consider an unsteady state process with a control volume consisting of both the turbine and the tank.
