Question

Choose the correct option
Assertion: Bernoulli's equation hold for non-steady and compressible flow.
Reason: For non-steady flow, velocity and pressure are constant with time.

• A. If both assertion and reason are true and reason is the correct explanation of assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of assertion.
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false.

Answer 1

The correct option is D If both assertion and reason are false.

Bernoulli's equation is valid only for steady, inviscous ad incompressible flows.
For non-steady flows, properties of flow vary with time. Thus both assertion and reason are false.
