- Based on the layout of the water supply system, as show in Figure 1, the pressure, in psi, is estimated be 46 at the faucet in the and floor of the residential building. Consider flow through the delivery pipe, Q = 1.50 cfs and diameter of the pipe, D = 2.65 inch with e = 0.015 inch. Ingore the minor pressure losses and use the following formulae to calculate the major pressure losses. The additional power in hp required to provide the recommended pressure of 58 psi at the building is nearly. Assume f = 0.0175. Use g = 62.4 lb/f3 for water.

Theeffective length—including fittings—of the commercial steel pipe is 6,000 ft. The dischargeat point 4 is 200 ft above the pump exit, which is level with the free surface of oil in thetanker. However, because of an intervening hill, point 3 is at a higher altitude than point 4.Losses between points 1 and 2 may be ignored.The crude oil has the following properties:Density ρ = 53 lbm/ft 3 ; Viscosity μ = 13.2 cP; Vapour Pressure Pv = 4.0 psia Answer the following questions:1. If the combination of pump and motor is 80% efficient, how much electrical power(kW) is needed to drive the pump?2.
