Water is to be pumped to the top of a building that is 366 m high. If the density of water is 1.00 x 103 kg/m3, what amount of pressure is needed in the water line at the base of the building to raise the water to this height

I'm assuming that you aren't considering any head losses and that this is a straightforward hydrostatics problem. If that's the case, the hydrostatic pressure of any body of liquid is related to its density and its height. P=p*g*z where p = density, g = gravity and z = height

hint: here we have to apply the theorem of Bernoulli: \[{z_1} + \frac{{{P_1}}}{{\delta g}} = {z_2} + \frac{{{P_2}}}{{\delta g}}\] where \delta is the water density, and g is the gravity: g=9.81 m/sec^2 or g=32 feet/sec^2 |dw:1434956101690:dw|
