Steam from a superheater at 7 bar. 300 t is mixed in steady adiabatic flow with wet steam at 7 bar, dryness fraction 0.9. Calculate the mass of wet steam required per kilogram of superheated steam to produce steam at 7 bar, dry saturated.
Wet stream (Saturated liquid-vapor mixture) at 2.00 Mpa is the initial state of a constant enthalpy process. The end state is at 0.100 Mpa, 150?. Determine the quality of the wet stream (i.e. the initial state)
A pump operating at steady state takes in saturated liquid water at 65 lbf/in.2 at a rate of 10 lb/s and discharges water at 1000 lbf/in.2 The isentropic pump efficiency is 80.22%. Heat transfer with the surroundings and the effects of motion and ..
