Ac cording to Bernoulli's theorem the pressure of water should remain uniform in a pipe of uniform radius. But actually it goes on decreasing, why is it so?

Text Solution

Verified by Experts

When water flows through a pipe, work is done against the viscous force. This work done is taken from the pressure energy. As a result of it, the pressure of the water falls. With onwards movement of water in pipe. It is due to this reason that a house located at a large distance from a water tank receives water at lower pressure than those houses located closer to water tank.

Ac cording to Bernoulli's theorem for the streamline flow of an ideal liquid, the sum of pressure energy/mass, kinetic energy/mass and potential energy /mass remains constant at every cross section, throughout the liquid flow. i.e., (P)/(rho) + (1)/(2)upsilon^2 + gh = cosntant, where the symbols have their usual meaning. Note that an ideal liquied is the one, which is perfectly incompressible, irrotational and non visous. Read the above passage and answer the following question ? (i) At what speed will the velocity head of a stream of water be equal to 40 cm ? (ii) What is the implication of Bernoulli's theorem in day to day life ?

The bulk modulus of a spherical object is B if it is subjected to uniform pressure p , the fractional decrease in radius is:

Fluids at rest exert a normal force to the walls of the container or to the sruface of the body immersed in the fluid. The pressure exerted by this force at a point inside the liqid is the sum of atmospheric pressure and a factor which depends on the density of the liquid, the acceleration due to gravity and the height of the liquid, above that point. The upthrust acting on a body immersed in a stationary liquid is the net force acting on the body in the upward direction.
