If 15.0 m3/min of steam at 450.0°C and 10.0 bar enters a turbine and leaves as saturated steam at 9.25 bar, what is the volumetric flow rate of steam leaving the turbine? If the turbine operates adiabatically, what is the work output?
The total power developed by the turbine is 11,400 kW. Kinetic and potential energy effects can be neglected. Determine the mass flow rate of the steam at each of the two exits, in kg/h.
