Oxygen flows isentropically through a 100 mm −diameter pipe. At one point, the velocity of flow, pressure , and unit weight are 125 m/s,  450 kPa, and 0.058 kN m3 ⁄ , respectively. At another point a short distance away from the first, the pressure is 360 kPa. Determine the velocity at the second point.

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.
