A piston is moving through a cylinder at a speed of 18 ft/s. The film of oil separating the piston from the cylinder has a viscosity of 0.021

Q: Calculate the dynamic and kinematic viscosity of water at 53.85°C

A:

Q: Liquld A Is known to have a lower surface tension and lower viscosity than Liquid B. Use these facts…

A: Surface tension: The attraction of the particles in the surface layer by the bulk of the liquid,…

Q: The Newton's law of viscosity can be expressed in mathematical form as T=u (dv/dv)

A: This question is based on the concept of Newton's law of viscosity.

Q: What methods exist to calculate the viscosity of dense gases and liquids?

A: Viscosity: It is defined as the resistance or opposition offered by liquid to the flow. When there…

Q: ii. By applying a thick oil film as shown in figure Qlb-(b), the force required to push the block…

A: We have to determine the oil layer thickness

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.
