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.

a) A suction pump. Consider a pipe that is inserted vertically into water. By suction, the pipe is evacuated of air. How high will the water rise? b) A water turbine is designed to extract kinetic energy from the hor- izontal flow of water and convert it into rotation of the turbine. You may assume that the height of the fluid does not change as it flows through the turbine, and that the fluid is incompressible. If the velocity is lowered from 100 m/s to 70 m/s as the fluid flows through the turbine, what is the change in pressure? c) Is the pressure higher upstream or downstream? d) The fluid in (b) is replaced by air to make a wind turbine. What is the change in pressure now for the identical change in velocity to (b)?
