Determination of Coefficient of Viscosity of Water by Poiseuille’s Flow Method
A capillary tube of a very fine bore is connected by means of a rubber tube to a burette kept vertically. The capillary tube is…

Explain Poiseuille’s Equation
Poiseuillie investigated the steady flow of a liquid through a capillary tube. He derived an expression for the volume of the liquid flowing per second…

Experimental Determination of Viscosity of Highly Viscous Liquids
The coefficient of highly viscous liquid like castor oil can be determined by Stoke’s method. The experimental liquid is taken in a tall, wide jar.…

Explain Stoke’s Law for Highly Viscous Liquids
When a body falls through a highly viscous liquid, it drags the layer of the liquid immediately in contact with it. This results in a…

Describe on Reynold’s Number
Reynolds number is a pure number which determines the type of flow of a liquid through a pipe. It is denoted by NR. It is…

Applications of Pascal’s Law
According to Pascal’s law, “The outer static pressure applied on a confined liquid is distributed or transmitted consistently throughout the liquid in all directions.” The…

Describe on Turbulent Flow
When the velocity of a liquid exceeds the critical velocity, the path and velocities of the liquid become disorderly. At this stage, the flow loses…
