To supply the plumbing system of a New York office building, water needs to be pumped to a tank on the roof, where its height will provide a "head" of pressure for all the floors. The vertical height between the basement pump and the level of the water in the tank is 95.3 m. What gauge pressure does the pump have to apply to the water to get it up to the tank?
Should my answer be: P=pgh= (1000kg/m3)(9.80m/s2)(95.3)= 9.34e5 ?
If not, can someone show me what I did wrong. I used 1000 as my density of water, and 9.80 as gravity
You did it correctly. The dimension of the final pressure number is Pascals
