A monometer connected to a closed tap reads

4.5 \times {10^5}pascal

. When the tap is opened the reading of the monometer falls to

4 \times {10^5}pascal

. Then the velocity of flow of water is

View answer and explanation

Correct option: D

10m{s^{ - 1}}

Option D (

10m{s^{ - 1}}

) is correct because it is calculated using Bernoulli's equation, relating pressure difference to fluid velocity.

With the increase in temperature viscosity of a liquid - Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.

Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.

In the light of the above statements, choose the most appropriate answer from the options given below. Hydraulic lifts and hydraulic brakes are based
