In the supply system (Q=0.89cfs) shown in the figure, the pressure required at the delivery end is 65psi. Consider the entrance and exit losses and a water temperature of 70°F, determine: The pumping head and The power delivered by the pump (efficiency 0.62) 10ft Solution: 4-in. 1000 ft commercial steel Sat 1. Velocity of the flow in pipe is v= 2. Major loss hf: A o Darcy-Weisback equation method: 1. Roughness of commercial steel is e=2X10-4ft; 2. At 70F, kinematic viscosity of water is v=1.06X10-5ft²/s; 3. Relative roughness is & = ft/s; 4. Reynolds number is Re= X105; 5. From Moody diagram, frictional factor f= ft. 6. Thus hf= o Hazen-Williams equation (C=105): 1. hf= ft.
