In flat areas, water towers are used to supply water to houses. Water is pumped into the tower, and then directed from the tower to houses so that when people turn the water on there is water pressure. The top of the tower is vented to the atmosphere. (a) What is the gauge pressure (total pressure minus atmospheric pressure) at each of the two houses? (in Bernoulli's equation, if the water is not running, you can set v = 0 on both sides, and the external pressure in the water tower is just atmospheric pressure). (b) If a faucet is circular with diameter of 2.0 cm, what is the velocity of the water in each house? You can assume that the velocity of water within the tower is negligible.
