Formula
P₁ + ½ρv₁² + ρgh₁ = P₂ + ½ρv₂² + ρgh₂
Worked example
Using the values pre-filled in the calculator above:
- Pressure at point 1 = 200,000 Pa
- Velocity at point 1 = 2 m/s
- Height at point 1 = 0 m
- Velocity at point 2 = 8 m/s
- Height at point 2 = 3 m
- Fluid density = 1,000 kg/m³
the calculator returns:
- Pressure at point 2: 140,580.1 Pa
- In bar: 1.4058
- Pressure drop: 59,420 Pa
- Dynamic pressure at 2: 32,000 Pa
