Concept:To simplify complex fluid mechanics equations (like deriving Bernoulli's equation), physicists define an 'ideal' fluid using a strict set of assumptions.
Formula:$$ \text{N/A} $$
Solution:- Incompressible: Density (\( \rho \)) cannot change; it doesn't compress under pressure.
- Non-viscous: There is zero internal friction between adjacent fluid layers, meaning no energy is lost to heat.
- Steady flow: Velocity at any given point is constant over time, avoiding turbulence.
- Irrotational: The fluid has zero angular momentum about any internal center.
- Therefore, all of the mentioned properties collectively define an ideal fluid.
Why other options are incorrect:While Options A, B, and C are each correct traits, selecting only one ignores the others. The concept demands all of them simultaneously.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
