A water tower that is 90 ft high provides water to a residential subdivision. The water main from the tower to the subdivision is 6 in. sch 40 steel, 3 miles long. If each house uses a maximum of 50 gal/h (at peak demand) and the pressure in the water main is not to be less than 30 psig at any point, how many homes can be served by the water main?

Question
A water tower that is 90 ft high provides water to a residential subdivision. The water main from the tower to the subdivision is 6 in. sch 40 steel, 3 miles long. If each house uses a maximum of 50 gal/h (at peak demand) and the pressure in the water main is not to be less than 30 psig at any point, how many homes can be served by the water main? Following are the number of valves and fittings: 2 standard 90-degree elbows Two completely open valves, one after the tank and the other before exiting the water main 29 standard coupling (K= 0.04) You noticed that the current piping system, which is above the ground, is vulnerable to tampering. Two couplings and two standard 90-degree elbows would be required if the water main was buried 6 feet underground. Will you be able to serve the same number of households as you did previously? Why? Please start by stating all of your assumptions and design considerations. Tips: Solve both conditions Underground and ground
