Apump draws water from a storage tank (water surface elevation= 70 ft) through a 6-inch pipe. the pump is at an elevation of 50 ft and its 4-inch diameter delivery pipe terminates at a 3 inch diameter nozzle at an elevation of 80 ft. head losses amount to 5 v^2g in the 6 inch pipe and 12 v^2/2g in the 4 inch pipe. if the pump develops a head of 80 ft, what is the system discharge?

Water (temperature=68f) is pumped from a reservoir to a storage tank atop a building by means of a centrifugal pump. there is 200-ft difference in elevation between the two water surfaces. the inlet pipe at the reservoir is 8ft below the surface, and local conditions are such that the level is substantially constant. the storage tank is vented to the atmosphere and the liquid level is maintained constant. the inlet pipe to storage tank in 6ft below the surface. the piping system consists of 200-ft of 6-in sched. 40 steel pipe containing 2 90o elbows and open gate valve from the reservoir to the pump, 6-in pipe follows the pump for a length of 75-ft after after which pipe size is reduced to 4-in for 250-ft to the tank. the 4-in pipe contains one open gate valve and 3 90o elbows. it is desired to maintain 625 gpm water flow. if the pump-motor set has overall efficiency of 60% a. determine the kw and hp rating of the pump. b. what would be the pumping cost be per day if electricity costs p3.00/kwhr?

20% 2. at night, water is pumped from a treatment plant reservoir through distribution piping to an elevated storage tank. the water surface in the supply reservoir is at 10-ft elevation; the lift-pump elevation is 20 ft; the water level in the elevated tank is at 140 ft elevation. the pipe network may be considered equivalent to 5000 ft of 10-in diameter cast-iron pipe (c = 100). calculate the pump discharge pressure needed to supply a flow of 1000 gals/min to the tank.
