If the velocity head of a stream of water is equal to 10 cm, then its speed of flow is (

\mathrm{g} = 10\mathrm{m}{\mathrm{s}^{ - 2}}

)

View answer and explanation

Correct option: C

1.4\mathrm{m}{\mathrm{s}^{ - 1}}

Option C (

1.4\mathrm{m}{\mathrm{s}^{ - 1}}

) is correct because it is the result of calculating the speed of flow using the given velocity head and the formula relating velocity head to speed.

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
