A centrifugal pump is used to extract water from a reservoir at 14,000 gal/min. The pipe connecting the pump inlet to the reservoir is 12 inches in diameter and is 65 ft long. The average friction factor in this pipe is 0.018. The pump performance curves indicate that, at this flow rate, the head rise across the pump is 320 ft, the efficiency is 81% and the required NPSH is 25 ft. Please estimate:1) The required brake horsepower.2) The location of the pipe inlet with respect to the water surface in the reservoir for cavitation to be avoided. Illustrate your answer with a sketch. You may assume that the pump will be operated at 20°C where the vapor pressure is 49 psf and the atmospheric pressure is 2126 psf (pound per square foot).1400 bhp, -21 ft
