Cum se calculează Bernoulli Equation

Ce este Bernoulli Equation?

Bernoulli's principle states that in a flowing fluid, faster flow means lower pressure. It explains aircraft lift, carburettors, Venturi meters, and why shower curtains billow inward.

Formulă

P(X=k) = C(n,k) × p^k × (1−p)^(n−k) | μ = n×p | σ² = n×p×(1−p)

n: Number of trials
k: Number of successes
p: Probability of success (0–1)
C(n,k): Binomial coefficient (n choose k)

Ghid pas cu pas

1P₁ + ½ρv₁² + ρgh₁ = P₂ + ½ρv₂² + ρgh₂
2ρ = fluid density (water: 1,000 kg/m³)
3Higher velocity → lower static pressure (Venturi effect)
4Assumes incompressible, non-viscous, steady flow

Exemple rezolvate

Intrare

Pipe narrows from 0.1m² to 0.04m², v₁=2m/s

Rezultat

v₂ = (0.1/0.04) × 2 = 5 m/s; pressure at narrow section drops
