This tool helps you compute and optimize process engineering calculations efficiently.
Process Engineering Calculator
This calculator computes the pressure drop in a pipe based on fluid flow rate, pipe diameter, fluid density, fluid viscosity, length of the pipe, and pipe roughness.
How to Use
Enter the following parameters in the provided fields:
- Fluid Flow Rate (Q) — The rate at which the fluid is flowing through the pipe in cubic meters per second (m³/s).
- Pipe Diameter (D) — The diameter of the pipe in meters (m).
- Fluid Density (ρ) — The density of the fluid in kilograms per cubic meter (kg/m³).
- Fluid Viscosity (μ) — The dynamic viscosity of the fluid in pascal-seconds (Pa·s).
- Length of Pipe (L) — The length of the pipe in meters (m).
- Pipe Roughness (ε) — The roughness of the pipe’s interior surface in meters (m).
After entering all the required parameters, click the “Calculate” button to obtain the pressure drop across the pipe in pascals (Pa). The result will be displayed in the “Result” field.
How It Calculates the Results
The calculator first determines the cross-sectional area of the pipe and the fluid velocity. Using these values, it computes the Reynolds number, which is essential for identifying the flow regime (laminar or turbulent). Depending on the Reynolds number, the friction factor is calculated using appropriate formulas. Finally, it calculates the pressure drop using the Darcy-Weisbach equation.
Limitations
This calculator assumes steady, incompressible flow and does not account for changes in the fluid properties due to temperature or pressure variations. It is ideal for engineering estimations but may not be suitable for highly specialized or safety-critical applications requiring rigorous precision.
