Air enters a fan through a duct  velocity of 6.3 m/s and an inlet static  pressure of 2.5cm of water less than the  atmospheric pressure. The air leaves the fan  through the duct at a velocity of 11.25 m/s  and a discharge pressure of 7.62cm of water  above the atmospheric pressure. If, the  density of the air is 1.2kg/m3 and the fan  delivers 9.45m3 /s, what is the fan efficiency  when the power input to the fan is 13.75 kW  at the coupling.

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.
