Based on the layout of the water supply system, how much pressure in psi will be available at the faucet of the 2nd floor of the residential building as show in Figure 1 below? The pressure at the source is 75 psi.  Do you think that the pressure is enough for the building? Consider flow through the delivery pipe, Q = 3.75 cfs and diameter of the pipe, D = 4.25 inch. Ignore the minor pressure losses and use the following formulae to calculate the major pressure losses. If the pressure on the 2nd floor is not with the standard limit of 50 – 60 psi, a pump needs to be added in the place 65 ft from the source, as shown. Estimate the pump power in horsepower to provide a pressure of 58 psi in the house

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
