4.) A pumping system is designed to pump from a storage reservoir located at an elevation of 2030 feet. The pump elevation is 2015 feet. The pump discharge flowrate is 4200 gpm and the water temperature is 80˚ F. Between the storage tank and the pump is 25 feet of 12-inch DIP pipe (f = 0.014) with one (1) rounded entrance (Kent = 0.25) and two (2) 45-degree bends (Kbend = 0.20). What is the NSPHA for this system?

Water from a pond is to be pumped into a reservoir at an elevation of 17 m. Approximately 30 m^3 of water is needed in the morning for irrigating a greenhouse over a period of one hour. The same amount and irrigation rate are needed again in the afternoon. The piping passage requires twelve 90-degree elbows and seven Tees. Design a workable system.

A pumping system is designed to pump from a storage reservoir located at an elevation of 1015 feet. The pump elevation is 1005 feet. The pump discharge flowrate is 4500 gpm and the water temperature is 100˚F (1 atm). Between the storage tank and the pump is 30 feet of 14-in DIP pipe (f = 0.018) with one rounded entrance (kent = 0.05), and two 45 -degree bends (k45 = 0.30). What is the NPSH (in ft) for this system?...
