The sliding plate viscometer is used to measure fluid viscosity. The top plate (100 mm x 50 mm) is moving to the right with a constant velocity of 22 m/s in response to a force of 1 N. The bottom plate is stationary and separated by a vertical distance of 1 mm from the upper plate. What is the viscosity of the fluid? W F ng L moving plate stationary plate fluid

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.
