A pump is required to deliver 20°C water to an elevated storage tank. The water must be raised 44 m, and a I 50-m-long, ductile-iron pipe, 35 cm in diameter, is to be used. Determine the appropriate pump speed (based on the highest efficiency obtainable) and the operating conditions if pump Ill in Figure 5.24 is used. The suction line is JO m of the 150 m length, minor loss coefficients in the suction line total 3.7, and the discharge line contains only an exit loss.
