He efficiency of a steam power plant can be increased by bleeding off some of the steam that would normally enter the turbine and usingit to preheat the water entering the boiler. in this process, liquid water at 50oc and 1000 kpa is mixed with superheated steam at 200oc and 1000 kpa. if the plant operators want to produce a saturated liquid at 1000 kpa, what ratio of mass flow rates of water and superheated steam are required?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
