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.

6.69 Water flows steadily through the reducing elbow
shown. The elbow is smooth and short, and the flow accel-
erates; so the effect of friction is small. The volume flow rate
is Q=2.5 L/s. The elbow is in a horizontal plane. Estimate
the gage pressure at section.
