The main waterline into a tall building has a pressure of 600 kPa at 5-m elevation below ground level. How much extra pressure (kPa) does a pump need to add to ensure a waterline pressure of 200 kPa at the top floor 150 m aboveground?
Added by Larry A.
Step 1
Given: Initial pressure at 5m below ground level = 600 kPa Height of the building = 150m Density of water = 998 kg/m^3 Acceleration due to gravity, g = 9.81 m/s^2 Using the hydrostatic pressure formula: P = P0 + Ļgh where: P = total pressure at the top floor P0 = Show moreā¦
