Pump problem-2 Thursday, July 21, 2022 9:26 PM Problem. The water system in a suburban area consist of an old 20 cm pipeline 750 m long which conveys water from a pump to a reservoir whose water surface is 105 m higher than the pump. Water is pumped at the rate of 70 liters/sec. Neglecting minor losses. a. Determine the head added by the pump using the 20 cm pipeline. Assume f = 0.033. b. If the old pipe is replaced with a new 25 cm ∅ pipe, compute the energy supplied by the pump. From <https://www.facebook.com/groups/fluidmechanics2> Solution: B L=750 m Q= 70L/s= 70x10-3m3/s Friction factor, f= 0.033 ZB=105m PUMP A a. Determine the head added by the pump using the 20 cm pipeline. Bernouli and Energy Eqn Page 1 Bernouli and Energy Eqn Page 2 b.
