Q2- Calculate the dynamic viscosity of an oil, which is used for lubrication between a square plate of size 0.8m X 0.8m and an inclined plane with angle of inclination 30℃ as shown in figure. The weight of square plate is 300 N and it slides down the inclined plane with a uniform velocity of 0.3 m/s. The thickness of oil film is 1.5 mm.
Viscosity -
It is the property of fluid which offers resistance to the movement of one layer of fluid over another adjacent layer of the fluid.
Shear stress is proportional to the rate of change of velocity with respect to y. it is denoted by symbol τ (tau)
