Superheated steam at 40 bar absolute and 500°c flows at a rate of 250 kg/min to an 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 to its initial temperature. neglect kinetic energy changes. a. write an energy balance on the turbine and use it to determine the outlet stream temperature. (7 marks) b. write an energy balance on the heater and use it to determine the required input power (kw) to the steam. (6 marks) c. verify that an overall energy balance on the two-unit process is satisfied. (6 marks) d. suppose the turbine inlet and outlet pipes both have a diameter of 0.5 meter. show that it is reasonable to neglect the change in kinetic energy for this unit
