Calculate the size (P, in horsepower) of a pump required to move water moving at the average velocity of 10 feet per second (Vavg-10 ft/s) through a 5000-foot long pipe (L-5000 ft) with a l- inch inside diameter (D-1 in). Assume that the viscosity of water is 0.01 poise at room temperature (H-0.01 poise) and that the pump has an efficiency of 0.7 (n-0.7). Problem solving steps to follow: (1) Calculate the Reynolds Number (Re) using the formula: DVP Re = Where Di is the inside diameter of the pipe, Vavg is the average velocity of water, p is the water density (p-1000 kg/m'), andu is the water viscosity. Re is dimensionless so make sure that the units of the given values cancel out.
