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 (m
^{3}/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/m
^{3}). - 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/m^{3})**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.
