This tool calculates hydraulic parameters to help you design efficient fluid systems.
How to Use the Hydraulic Calculator
To use the hydraulic calculator, follow these steps:
- Enter the flow rate in cubic meters per second (m3/s).
- Enter the pipe diameter in meters (m).
- Enter the pipe length in meters (m).
- Enter the pipe roughness in meters (m).
- Enter the fluid viscosity in Pascal-seconds (Pa.s).
- Enter the fluid density in kilograms per cubic meter (kg/m3).
- Click “Calculate” to see the pressure drop result.
How It Works
The calculator uses the Darcy-Weisbach equation to compute the pressure drop across a given length of pipe. The equation is:
ΔP = f * (L/D) * (ρ * v² / 2)
Where:
- ΔP = Pressure drop (Pa)
- f = Darcy friction factor (calculated using the Colebrook-White equation)
- L = Pipe length (m)
- D = Pipe diameter (m)
- ρ = Fluid density (kg/m3)
- v = Fluid velocity (m/s)
Limitations
This hydraulic calculator assumes steady-state, incompressible flow and is applicable for Newtonian fluids. It does not account for complex flow conditions like turbulent or transient flow in detail. Use it as an approximation and consult a fluid dynamics specialist for more precise calculations.
