What Is Viscosity Of A Liquid?
Viscosity: When the motion of a liquid over a fixed horizontal surface is slow and steady, i.e, when the motion of a liquid over a fixed horizontal surface is streamline,…

Define Coefficient Of Viscosity Of A liquid, Its Dimension And Units.
Coefficient of viscosity: Let us consider a region of a liquid flowing in streamline motion parallel to the X-Y plane along the positive Y direction. Let us consider two adjacent…

Define The Units Of Coefficient Of Viscosity In C.G.S. And S.I. Units.
Poise: If a tangential force of one dyne is required per sq. cm. to maintain a relative velocity of 1 cm/sec between two layers 1 cm. apart, then the coefficient…

What Are Newtonian And Non-Newtonian Liquids?
Newtonian & Non-Newtonian liquids: The coefficient of viscosity of a liquid is given by , or, . where, is the dragging force acting in contact area of two adjacent layers,…

What Do You Mean By Streamline And Turbulent Motion Of A Liquid?
Laminar or Streamline motion: If a liquid flows in such a way that its velocity at any point in the liquid is always the same in direction as well as…
-
What is Critical Velocity?
Critical Velocity: Critical velocity of a fluid is the maximum velocity of flow above which the flow ceases to be streamlined and becomes turbulent.

What Is Reynold’s Number? Explain The Significance Of Reynold’s Number.
Reynold’s Number: Experimentally, it is found that the critical velocity of a liquid depends upon its coefficient of viscosity , density of the liquid , and the diameter of the…

Distinguish Between Streamline And Turbulent Motion With Special Reference Of Reynold’s Number.
Distinguish between streamline and turbulent motion: If a liquid flows in such a way that its velocity at any point is always the same in magnitude as well as in…
