The rate of flow of liquid in a tube of radius

r

, length

l

, whose ends are maintained at a pressure difference

p

is

V=\frac{\pi N p r^4}{\eta l}

, where

\eta

is coefficient of the viscosity and

N

is

View answer and explanation

Correct option: B

\frac{1}{8}

Option B (

\frac{1}{8}

) is correct because the correct formula for the rate of flow of liquid is

V=\frac{\pi p r^4}{8 \eta l}

.

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
