Please hep me solve this problem i will really appreciate it

Extracted text: 15. A pump operating at 660 hp delivers water, from a large pressurized supply tank to a large pressurized reservoir, at a rate of 150 ft’/s. Total length of the suc- tion and the discharge piping is 1000 ft. Pressures in the supply and the reservoir tanks are 30 psig and 15 psig, respectively. These pressures are maintained throughout the pumping process. Water level heights with respect to the pump centerline are 15 ft and 50 ft, respectively. Find the pipe diameter. Ignore varia- tions in water level in both tanks. [Ans.: D; = 3.5 ft]. Air Water Discharge piping H, Air Gate Check Valve Water Suction Valve H. piping, Pump
