Effect of temperature on co-efficient of viscosity in Gases The effect of temperature on gases is opposite to that of liquid. In case of gases…

Effect of temperature on co-efficient of viscosity in Liquids Co-efficient of viscosity is affected by temperature. Experimental results show that with the increase of temperature…

Necessity of viscosity Viscosity is the measure of a substance’s resistance to motion under an applied force. (1) Design and construction of boats, steamers, launches,…

Co-efficient of Viscosity Definition: For unit velocity gradient the amount of viscous force that acts per unit area of a fluid is called co-efficient of…

Viscosity or Internal Friction Definition: The property of a fluid which tries to oppose or retard relative velocity between different layers inside the fluid is…

Theoretical Explanation of Terminal Velocity From Stokes law – “the force required to move a sphere through a given viscous fluid at a low uniform…

Dependence of Terminal Velocity (a) Terminal velocity at a point is inversely proportional to the coefficient of viscosity. (b) Terminal velocity is directly proportional to…

Terminal Velocity We know, a falling body travels downward due to the influence of gravitational force. So, when a body continues to fall down through…

Characteristics of Turbulent Motion with Explanation Turbulent Motion is the speed of the fluid at a point is continuously undergoing changes in both magnitude and…

Turbulent Motion While travelling through river sometimes eddy is observed. Again some people might have seen surge or tidal bore of the sea. It is…
