Bernoulli کا حساب کیسے لگائیں
Bernoulli کیا ہے؟
Bernoulli's equation relates pressure, kinetic energy, and potential energy in flowing fluids. It explains how airfoils generate lift and how pumps function.
فارمولا
The calculator applies P₁ + ½ρv₁² + ρgh₁ = P₂ + ½ρv₂² + ρgh₂
مرحلہ وار گائیڈ
- 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

ان پٹ
P₁ = 101.3 kPa, v₁ = 0, z₁ = 0, P₂ = ?, v₂ = 10 m/s, ρ = 1 kg/m³
نتیجہ
P₂ ≈ 101.3 - 50 = 101.25 kPa
Lower pressure in moving fluid
عام غلطیاں جن سے بچنا ہے
- ✕Applying Bernoulli to compressible gases without corrections
- ✕Neglecting elevation terms in vertical flow
اکثر پوچھے جانے والے سوالات
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.
