Bernoulli pressure change
Estimate the pressure change between two points along a streamline in an ideal steady flow.
Method and scope
p₂ − p₁ = ½ρ(v₁² − v₂²) + ρg(h₁ − h₂).
Use bernoulli pressure change for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Fluid density — kg/m³
- Velocity at point 1 — m/s
- Velocity at point 2 — m/s
- Elevation at point 1 — m
- Elevation at point 2 — m
SOURCE AND LIMITS
Assumptions: Flow is steady, incompressible, frictionless, and compared along one streamline. The answer is p₂ − p₁.
Limitations: Use a loss-inclusive energy equation and qualified review for real system design.
