Water towers store water above the height of most consumers for times of heavy use, eliminating the need for high-speed pumps. In this problem use for the density of water and g for the gravitational acceleration.

a) What is the height, h, in terms of the variables given in the introduction, that the water level in such a tower must have above a user in order for the user to receive water at gauge pressure P?

b) What is the height, in meters, if the gauge pressure required is 2.8 x 10⁵ Pa?
