0.4 Superheated steam at 40 bar absolute and 500 C flows at a rate of 185.95 kg/min to and adiabatic turbine, where it expands to 5 bar. The turbine develops 1500 kW. From the turbine the steam flows to a heater, where it is reheated isobarically (at constant pressure) to its initial temperature. Neglect kinetic energy changes. (a) Draw and label the process flowchart. (b) Write an energy balance on the turbine and use it to determine the outlet stream temperature (e) Write an energy balance on the heater and use it to determine the required heat input (kW) to the steam. (d) Verify that an overall energy balance on the two-unit process is satisfied. (e) Suppose the turbine inlet and outlet pipes both have diameters of 0.5 m. Show that it is reasonable to neglect the change in kinetic energy for this unit
