A smooth plastic pipe is to be designed to carry 10 (ft^3)/s of water at 77°F(25°C) through 1800 ft of horizontal pipe with an exit pressure at 25 psig. The pressure drop is to be approximately -300 psig. Determine the minimum pipe diameter (in inches) that will result in the given pressure drop. For water at 77°F: ρ = 1.934 slug/(ft^3), and μ = 1.86E-5 slug/(ft-s).

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.
