I am given a problem about a booster fan in a circular duct with a diameter of 30cm. The work done on the system by the fan is 80 W, causing an increase of pressure on the outlet side of the fan of 70 Pa. All other work and energy is negligible. How do I find the maximum velocity of the air in the duct?

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
