Paano Kalkulahin si Bernoulli
Ano ang Bernoulli?
Bernoulli's equation relates pressure, kinetic energy, and potential energy in flowing fluids. It explains how airfoils generate lift and how pumps function.
Pormula
The calculator applies P₁ + ½ρv₁² + ρgh₁ = P₂ + ½ρv₂² + ρgh₂
Step-by-Step na Gabay
- 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
Mga Nalutas na Halimbawa
Input
P₁ = 101.3 kPa, v₁ = 0, z₁ = 0, P₂ = ?, v₂ = 10 m/s, ρ = 1 kg/m³
Resulta
P₂ ≈ 101.3 - 50 = 101.25 kPa
Lower pressure in moving fluid
Mga Karaniwang Mali na Dapat Iwasan
- ✕Applying Bernoulli to compressible gases without corrections
- ✕Neglecting elevation terms in vertical flow
Mga madalas itanong
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.
