Assertion : Bernoulli's theorem is applicable only on laminar flow.
Reason : Laminar flow is consider to be non viscous.

Options

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

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states: "Bernoulli's theorem is applicable only on laminar flow."

- **Understanding Bernoulli's Theorem**: Bernoulli's theorem applies to fluid flow under certain conditions. It is applicable to both laminar and turbulent flows, provided the flow is steady, incompressible, and along a streamline.
- **Conclusion**: The assertion is **false** because Bernoulli's theorem is not limited to laminar flow; it can also apply to turbulent flow under the right conditions.

### Step 2: Analyze the Reason
The reason states: "Laminar flow is considered to be non-viscous."

- **Understanding Laminar Flow**: Laminar flow is characterized by smooth, orderly fluid motion where layers of fluid slide past one another. However, this does not mean that the flow is non-viscous. In fact, laminar flow involves viscous forces, and the viscosity of the fluid plays a significant role in this type of flow.
- **Conclusion**: The reason is also **false** because laminar flow is not considered non-viscous; it has viscosity that affects the flow behavior.

### Final Conclusion
Since both the assertion and the reason are false, the correct answer to the question is that both the assertion and reason are false.

### Summary of the Solution
1. The assertion that Bernoulli's theorem is applicable only to laminar flow is false.
2. The reason that laminar flow is considered to be non-viscous is also false.
3. Therefore, both the assertion and reason are false.
