How to Use This Calculator

Enter Flow Rate (kg/h), Pipeline Length (km), and Inlet Pressure (bar).
Set Outlet Pressure (bar).
Review the Pipe Diameter (mm) result.
Use Flow Velocity (m/s) and Pressure Drop (bar) to inform your decision.
Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Flow Rate (kg/h)

Flow Rate (kg/h): Mass flow rate of hydrogen through the pipeline in kg per hour.
Pipeline Length (km): Total length of the hydrogen pipeline in kilometers.
Inlet Pressure (bar): Pressure at the pipeline inlet after compression.
Outlet Pressure (bar): Required minimum pressure at the pipeline outlet.
