For a very rough pipe wall the friction factor is constant at high Reynolds numbers. For a pipe of diameter D1 the pressure drop over the length is p1. If he diameter of the pipe is then reduced to one-half the original value what is the relation of the new pressure drop p2 to the original pressure drop p1 at the same mass flow rate

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.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
