Homework 9 Water towers store water so pumps may run only when needed, rather than continuously. The figure shows a diagram of a water tower. Water has a density of pw 1. A worker periodically tests the water at the test point at the base of the tower. What is the pressure of the water at this point? (gauge pressure) 2. The worker leaves the valve open for a while to clear ale Figure 1: A cross section of a water tower is shown. The testing line leads from near surface of the wa- out the water that has been sitting in the pipe leading to the ter in the lower to value the han The Looth testing point.
