For a pumper truck pumping water to a fire, the back pressure is the additional pressure on the pump caused by the height of the nozzle. (Another way of thinking of back pressure is as the minimum pressure the pumper must produce in order to make water flow out the end of the nozzle.) Consider a pumper at street level pumping water through a hose to firefighters on the top of the ninth floor of a building. If each floor is 16 feet high, what is the head of water at the mouth of the nozzle?

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
