Estimate the supply pressure required at this flow rate

Reference no: EM13546950

Water, at volume flow rate Q=20 L/s, is delivered by horizontal fire hose and nozzle assembly. The hose (L = 100m, D = 75 mm, and e/D = .004) is made up of five 20 m sections joined by couplings. The entrance is squared edged; the minor loss coefficient for each coupling is Kc = 0.5, based on mean velocity through the hose. The nozzle loss coefficient is Kn = .02, based on velocity in the exit jet, of D2 = 25 mm diameter. Assuming the water temperature is 15 degrees C, estimate the supply pressure required at this flow rate.
