Accurately determine the dynamic pressure (PSI) generated by a specific fluid flow rate in a pipe or conduit with our user-friendly calculator. Essential for engineers, plumbers, and hobbyists involved in designing or analyzing hydraulic systems, irrigation networks, or pump performance where understanding the pressure component due to velocity is crucial.
Formula:
The calculator uses the dynamic pressure formula, which represents the pressure component due to the kinetic energy of the fluid:
P = 0.5 ⋅ ρ ⋅ v²
Where:
- P = Dynamic Pressure (pounds per square inch, PSI)
- ρ (rho) = Fluid Density (pounds per cubic foot, lb/ft³)
- v = Fluid Velocity (feet per second, ft/s)
The fluid velocity v is derived from the Flow Rate (Q) and Cross-sectional Area of the pipe (A): v = Q / A.
And the Cross-sectional Area A is calculated from the internal pipe diameter (D): A = π ⋅ (D/2)².
