a) Pressure is the weight of a 1 meter square column of water. The height of the pipe is 2311-564 = 1747 m volume is 1747 m³ density of water is density of water at 20C = 0.998 g/cm³ = 998 kg/m³ mass of water is 1747 m³ x 998 kg/m³ = 1744000 kg weight of water is 1744000 x 9.8 = 17090000 N Pressure is 17090000 N/m² or 17.09 MP b) Cross sectional are of pipe is A = πr² A = π(.065)² = 0.0133 m² one meter of pipe has a volume of .0133 m³ 4300 m³ are pumped per day The water in that one meter of pipe has to be changed 4300 / 0133 = 324000 times per day to handle the flow That is 324000 / (24*3600) times per second or 3.75 times per second. Since the section of pipe is is 1 meter, that is 3.75 meters per second.s
