Jinsi ya kukokotoa Bernoulli
Bernoulli ni nini?
Bernoulli's equation relates pressure, kinetic energy, and potential energy in flowing fluids. It explains how airfoils generate lift and how pumps function.
Fomula
The calculator applies P₁ + ½ρv₁² + ρgh₁ = P₂ + ½ρv₂² + ρgh₂
Mwongozo wa Hatua kwa Hatua
- 1Enter pressure, velocity, height, and fluid density at two points
- 2The calculator applies P₁ + ½ρv₁² + ρgh₁ = P₂ + ½ρv₂² + ρgh₂
- 3Results show energy conservation in fluid flow
Mifano Iliyotatuliwa
Ingizo
P₁ = 101.3 kPa, v₁ = 0, z₁ = 0, P₂ = ?, v₂ = 10 m/s, ρ = 1 kg/m³
Matokeo
P₂ ≈ 101.3 - 50 = 101.25 kPa
Lower pressure in moving fluid
Makosa ya Kawaida ya Kuepuka
- ✕Applying Bernoulli to compressible gases without corrections
- ✕Neglecting elevation terms in vertical flow
Maswali yanayoulizwa mara kwa mara
Why does faster-moving water have lower pressure?
Energy is conserved; faster kinetic energy means less pressure potential energy.
How do airplane wings use Bernoulli's principle?
Wings are curved to make air flow faster on top, creating lower pressure and generating lift.
