SOLVED:The net positive suction head required (N P S H R) by a pump may be expressed approximately as a parabolic function of volume flow rate. The N P S H R for a particular pump operating at 1800 rpm is given as Hr=H0=A Q^2, where H0=10 ft of water and A=7.9 ft / cfs^2 . Assume the pipe system supplying the pump suction consists of a reservoir, whose surface is 22 ft above the pump centerline, a square entrance, 20 ft of 6 -in. (nominal) cast-iron pipe, and a 90^∘elbow. Calculate the maximum v
