Each of these questions contains an Assertion followed by reason. Read them carefully and answer the question on the basis of following options, You have to select the one that best describes the two statements.

Assertion: The velocity of flow of a liquid is smaller when pressure is larger and vice-versa.

Reason: According to Bernoulli's theorem, for the streamline flow of all ideal liquid, the total energy per unit mass remains constant.

Solution

The correct option is D If Assertion is incorrect but Reason is correct.
Bernoulli's theorem is based on conservation of energy hence reason is true
velocity of liquid depends on both pressure and area so it is possible to reduce velocity and keep the same pressure.hence assertion is false
