2. A 25-mm diameter shaft with density 7,870 kg/m³ is pulled through a cylindrical bore as shown. Oil with a kinematic viscosity of 8.2 104 m²/s and SG-0.89 fills the 0.3-mm gap between the shaft and the bore. Find the magnitude of the force P required to pull the rod through the bore with a constant speed of 2.5 m/s. 0.5 m 15°

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.
