1. [7.5 points] Superheated steam at 40 bar absolute and 500C flows at a rate of 250kg/min to an adiabatic turbine, where it expands to 5 bar. The turbine develops 1500kW. From the turbine the steam flows to a heater, where it is reheated isobarically to its initial temperature. Neglect kinetic energy changes. (a) Write an energy balance on the turbine and use it to determine the outlet steam temperature. (b) Write an energy balance on the heater and use it to determine the required input (kW) to the steam. (c) Verify that an overall energy balance on the two-unit process is satisfied. 1.
