A steam-powered turbine is used to drive an electric generator. The steam flows in through an 8-cm diamter pipe to the turbine at a rate of 3.0 kg/s at 650°C and 1000 kPa. The steam exits through a 20-cm diameter pipe at 450°C and 100 kPa. If the turbine operates adiabatically, how much power (kW) can be generated by the turbine in this process?
