P₂ (same velocity)

150,375 Pa

v₂ (same pressure)

10.1 m/s

v₂ (P₂ = 0 gauge)17.46 m/s

Total Energy per Volume152,375 Pa

Dynamic Pressure (½ρv²)2,000 Pa

Hydrostatic Pressure (ρgh)49,050 Pa

How to Use This Calculator

Enter Pressure at Point 1 (P₁), Velocity at Point 1 (v₁), and Height at Point 1 (h₁).
Set Height at Point 2 (h₂) and Fluid Density.
Review P₂ (same velocity) (Pa) and v₂ (same pressure) (m/s).
Use v₂ (P₂ = 0 gauge) (m/s) and Total Energy per Volume (Pa) to inform your decision.
Use the chart to visualize the results and explore different scenarios by adjusting inputs.
