3) Problem # 11.43 on page 802 of Fluid Mechanics by White 9th Ed. (Fig. 11.7a is the same as the top figure on slide #4 of the lecture notes) The 28-in-diameter pump in Fig. 11.7a at 1170 r/min is used to pump water at 20C through a piping system at 14,000 gal/min. (a) Determine the required brake horsepower. The average friction factor is 0.018. (b) If there is 65 ft of 12- in-diameter pipe upstream of the pump, how far below the surface should the pump inlet be placed to avoid cavitation
