Exercise 6.2 (30%) Subcooled water first flows through an adiabatic choke valve and then into an adiabatic separator. Before the throttle valve, the water is at 5 MPa and 180°C and the mass flow is 200 kg/s. The throttle valve reduces the pressure to 300 kPa. This is also the pressure in the mass flows of steam and liquid out of the separator. a) Draw a sketch of the facility (remember to put numbers for conditions and relate to these in your use of symbols) and calculate the total volume flow of the water at the inlet to the throttle valve in m3/s. b) What is the temperature (°C) and steam quality of the water immediately after the throttle valve (before the inlet to the separator)? c) What are the mass flows of the liquid phase and the gas phase out of the separator in kg/s? d) The steam flow is expanded in an adiabatic turbine to 50 kPa and steam quality of 0.92. How much power does the turbine deliver in kW or MW?
