Water is to be delivered from an open air stand tank through a horizontal galvanized iron pipe to a building located 5000 ft away from the tank as shown in Figure P8.25. The water level in the tank is 50 ft above the ground level. The required flow rate is 1500 gpm and the required pressure in the line at the building is 15 psi. If the water temperature is 65°F, what is the minimum diameter of the pipe to meet these requirements?
