we needs to install a pump to feed water to a house. The plan is to pump water at night to fill a storage tank. The pipes and fittings has chosen to use for the installation are listed in the table below. The pumps in the pumping catalog are rated by their value of horsepower (hp). What is the minimum horsepower rating of a pump does capable of providing a flow rate of 5 gallons per minute of water at the tank? Assume the pump efficiency is 65% and that the pipe is PVC, i.e, completely smooth. (Assume: water: density =1g/cm3, viscosity =1 cp)
