Question: A hot-water stream at 160F enters an adiabatic mixing chamber with a mass flow rate of 4 lbm/s where it is mixed with a stream

A hot-water stream at 160°F enters an adiabatic mixing chamber with a mass flow rate of 4 lbm/s where it is mixed with a stream of cold water at 70°F. If the mixture leaves the chamber at 110°F, determine
(a) The mass flow rate of the cold water and
(b) The energy destroyed during this adiabatic mixing process. Assume all the streams are at a pressure of 50 psia and the surroundings are at 75°F.
