At a ski resort, water at 40 F is pumped through a 3-in diameter, 2000ft long, steel pipe from a pond at an elevation of 4286ft to a snow-making machine at an elevation of 4623ft at a rate of 0.26ft^3/s. It is necessary to maintain a pressure of 180 psi at the snow making machine. Determine the horsepower added to the water by the pump. Neglect minor loses.
