What is the Purpose of a Water Tower? (Hydrostatic Pressure Explained)

Ever wonder what the purpose of a water tower is? In this video we will go over the pupose, advantage and of water towers and complete a hydrostatic pressure problem to find the pressure of the water at the water towers base. Water towers serve two major purposes store water for later use and store potential energy. When ever you raise water off the ground the water gains potential energy. The water tower allows potential energy to be stored and maintain a water pressure at the base without the constant running of pumps. You only need to run a pump when the water level gets low. Lets go over a simple hydrostatic pressure problem. We are given the height of the water in the tower of 50 meters density of water of 1,000 kilograms a meter cubed and gravity of 9.81 meters per second per second. We need to find the pressure at the base of the water tower. So lets first go over how hydrostatic pressure works. If you were to have a meter cubed of water it would have a pressure of 9,810 N/m2 at its base. This means that the water is exerting a force of 9,810 N over the base of a metered squared on the ground So if we were to stack 3 meters of water on top of each other they would have 3 times the pressure. 29,430 N/m2 in this case. It is important to note with hydrostatic pressure that no matter what the shape of the tank of water as long as the water can flow continuously and the height of water is the same the pressure at the bottom of the tank will be the same. So both of these tanks depicted with a 3 meter height have the same pressure at the base. Going back to our problem if we take the density of the water multiply by gravity and then multiply times the height of the water we get a pressure of 490.6 kilopascals or 71.14 psi at the base of the water tower.
