Q1. A cylindrical body, 90 mm in diameter and 500 mm long and of weight 15 N, slides vertically down a 92 mm cylindrical sleeve due to its own weight. The space between the body and the sleeve is filled with oil. Determine the dynamic viscosity of the oil needed to restrict the velocity of fall of the cylindrical body to 5cm/s. (Assume linear variation of velocity across the gap).

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.
