Aclosed loop piping system has 50 ft of water (149.5 kpa) pipe friction loss, and a vertical height of 20 ft (6.1 m). what is the pump head pressure required related to this vertical rise? a. o ft of water (0 pa) b. 20 ft of water (59.8 kpa) c. 70 ft of water (209.2 kpa)

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.
