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.

Two plates are positioned at distance of 1.3 mm from each other. One of the plates is moving at velocity of 0.5 m/s; the movement requires a shear stress of 5 N/m². Calculate dynamic viscosity of the fluid between the plates by assuming linear velocity distribution. Round off the answer to three decimal digits in kg/ms, but enter the answer without the unit. Answer:
The velocity distribution of air between two parallel plates is linear. The top plate is moving with a velocity of 5.8 m/s and the distance between two plates is 0.1 cm. Find the shear stress at the lower wall if the dynamic viscosity of air is 2X10-5 N.s/m2. (your answer should be accurate to 5 decimal places)
