Solution
Correct Answer:
ρ g h
- Hydrostatic Pressure: Consider a parcel of fluid at rest. The weight of the fluid column above it exerts downward pressure.
- Derivation: P=Force/Area=(Mass×g)/A=(ρ×Volume×g)/A.
- Volume link: Since Volume =A×h:
- P=Aρ(Ah)g=ρgh.
- Conclusion: In a stationary incompressible fluid, the gauge pressure increases linearly with depth as ρgh.
