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.

Water at 70oF is pumped from a pressurized reservoir (4 psig) to a storage tank atop a building by means of a centrifugal pump. The level of water in the pressurized reservoir is 60 ft above the center-line of the pump. The piping system consists of 120 ft. equivalent length of 4" SCH 40 steel pipe containing two (2) globe valve (bevel-seat) and four (4) - 90o standard elbows and from the pressurized reservoir to the pump; 4" SCH 40 pipe follows the pump for an equivalent length of 25 ft. after which the pipe size is decreased to 3" SCH 40 steel pipe for an equivalent length of 260 ft. to the tank. The 3" SCH 40 pipe contains two (2) - 90o standard elbows.
