Ahot-water stream at 80°c enters a mixing chamber with a mass flow rate of 0.56 kg/s where it is mixed with a stream of cold water at 20°c. if it is desired that the mixture leave the chamber at 42°c, determine the mass flow rate of the cold-water stream. assume all the streams are at a pressure of 250 kpa. the enthalpies are 335.02 kj/kg, 83.915 kj/kg, and 175.90 kj/kg. the saturation temperature at a pressure of 250 kpa is 127.41°c.

The poppet of the pressure relief valve must move 0.2 in from the fully closed position in order to pass the full pump flow at the prv setting (full pump flow pressure). the poppet has a 0.85 in3 area on which system pressure acts. assuming that the relief valve cracking pressure should be 15% higher than the pressure required to overcome the hydraulic cylinder punching operation, find the required a) spring constant of the compression spring in the prv, b) initial compression of the spring from its free-length condition as set by the spring-adjustment mechanism of the prv (poppet held against its seat by spring).
