A windmill is operating in a 10 m/s wind that has a density of 1.2 kg/m3. The diameter of the windmill is 4 m. The constant-pressure (atmospheric) stream tube has a diameter of 3 m upstream of the windmill and 4.5 m downstream. Assume that the velocity distributions are uniform and the air is incompressible. Determine the thrust force on the windmill.
What is neutral buoyancy? Buoyancy is the net upward force experienced by an object submersed in a fluid. Pascal's principle dictates that fluid pressure on an object enhances
