Water flows through a tunnel in a reservoir of dam towards the turbine installed in the power plant. This is situated

{h} \mathrm{~m}

below the reservoir. If the ratio of cross-sectional areas of the tunnel at the reservoir and power station is

\eta

, find the speed of the water entering into the turbine.

View answer and explanation

Correct option: C

\eta \sqrt{\frac{2 g h}{\eta^2-1}}

Option C (

\eta \sqrt{\frac{2 g h}{\eta^2-1}}

) is correct because it is derived from applying Bernoulli's equation and the continuity equation.

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
