Why Do You Find Cloud Particles Floating In the Sky And Raindrops Falling Through The Air Instead Of Floating In It?
The tiny drops of water have a radius as small as 0.001cm and their terminal velocity when they fall through the air of coefficient of viscosity is about 1.2 cm/sec.…

State And Prove Bernoulli’s Theorem.
Bernoulli’s Theorem: In streamline motion of an incompressible liquid, the total energy of the liquid i.e., the sum of potential energy, kinetic energy and pressure energy remains constant at all…

State Torricelli’s Theorem.
Torricelli’s Theorem: This theorem states that the velocity of efflux of a liquid through an orifice is equal to the velocity which a freely falling body attains while falling through…

Show That The Speed Of A Liquid Coming Out Through A Hole At A Depth “h” Bellow The Free Surface In A Tank Is The Same As That Of A Particle Falling Through A Height “h” Under Gravity.
Torricelli’s Theorem: This theorem states that the velocity of efflux of a liquid through an orifice is equal to the velocity which a freely falling body attains while falling through…

Discuss The Effect Of Temperature And Pressure On Viscosity Of Liquid.
Effect Of Temperature: The viscosity of liquid decreases with increase in temperature. No definite relation has been found to exist between viscosity and temperature, but various emperical formulas have been…

Explain The Principle Of Venturimeter.
Venturimeter: Venturimeter is a device to measure the rate of flow of a liquid through a pipe based on Bernoulli’s theorem, as shown in Fig.1. It consists of a horizontal…
