At a ski resort, water at 40 degree F is pumped through a 3-in.-diameter, 2000-ft-long steel pipe from a pond at an elevation of 4286 ft to a snow-making machine at an elevation of 4623 ft at a rate of 0.26 ft3/s. If it is necessary to maintain a pressure of 180 psi at the snow-making machine, determine the horespower added to the water by the pump. Neglect minor losses.
