A 70-ft pipe must transport 2.4 cfs of 40°F water from a head tank to a cooling pond. The elevation difference between the tank and the pond is 4.2 ft. Determine the size of the commercial steel pipe that is required. Include entrance and exit connections and include a globe valve in the pipe.

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.
