Watch the units Consider a process consisting of a turbine (unit 1) and a heater (unit 2). Superheated steam 600°C and 10 bar enters the turbine at a mass flowrate of 300 kg/hr and leaves the turbine at 1 b The turbine works adiabatically and produces 3500 kW. The steam leaving the turbine enter heater (unit 2) to be rebeated isobarically (constant pressure) to its initial temperature of 600'C

Question
Watch the units Consider a process consisting of a turbine (unit 1) and a heater (unit 2). Superheated steam at 600°C and 10 bar enters the turbine at a mass flowrate of 300 kg/hr and leaves the turbine at 1 bar. The turbine works adiabatically and produces 3500 kW. The steam leaving the turbine enters a heater (unit 2) to be reheated isobarically (constant pressure) to its initial temperature of 600°C. a) Write an energy balance equation on the turbine and use it to determine the temperature of the outlet stream from the turbine. b) Write an energy balance on the heater and use it to determine the required heat input (kW) to the stream.
