Water (@75C) flows horizontally in a pipe at a rate of 1.6 m3 / min . The dia of the outlet is 2 inches. It enters a 3 inches 45 deg. elbow and is diverted upwards into a connecting pipe. If the pressure just before the elbow is 78 kPa, calculate the magnitude and direction of the force necessary to keep the elbow in place. Say, frictional losses in the elbow are negligible.

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.
