Liquid water at 20ºC, 100 kPa enters one inlet of an open-feedwater heater (a mixing chamber) with a flowrate of 0.5 kg/s. Superheated vapor at 200ºC is added at the other inlet. Determine the mass flowrate (in kg/s) of water vapor that must be added to produce a liquid-vapor mixture with a quality of 75% at the exit.

In steam power plants, open feedwater heaters are frequently used to heat the feedwater bylon mixing it with steam bled off the turbine at an intermediate stage. Consider an feedwater heater that operates at a pressure of 1000 kPa. Feedwater at 50°C and 1000 kPa is to be heated by mixing it with superheated steam at 200°C and 1000 kPa. In an ideal feedwater heater, the mixture leaves the heater as saturated liquid at the feedwater pressure. Determine the ratio...
