The Correct Option is
Solution and Explanation
Step 1: Understanding the Concept:
Bernoulli's principle relates pressure, velocity, and elevation in moving fluids. It is derived from the law of conservation of energy applied to an "ideal fluid".
Step 2: Detailed Explanation:
For Bernoulli's equation to be strictly applicable, the following assumptions are made regarding the fluid and its flow:
1. Incompressible: The density of the fluid must remain constant.
2. Non-viscous (Inviscid): There should be no internal friction between layers of fluid (zero viscosity).
3. Streamline Flow: The flow must be steady and laminar, not turbulent.
4. Irrotational: The fluid particles don't rotate about their own axes.
Step 3: Final Answer:
Bernoulli's equation holds good for non-viscous and incompressible fluids in streamline flow.
