Hose Capacity Calculator Calculator Usage Guide

Learn how to use the Hose Capacity Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the diameter of your hose in inches
  2. Input the length of the hose in feet
  3. Specify the initial pressure in PSI
  4. Provide the pressure drop across the hose in PSI
  5. Click the "Calculate" button to compute the flow capacity

Understanding the Results

  • Flow Coefficient (C): A dimensionless number that represents the efficiency of the hose
  • Flow Rate (GPM): The volume of water flowing through the hose per minute
  • Reynolds Number: Indicates if the flow is laminar or turbulent (values below 2000 are laminar)
  • Hose Velocity: The speed at which water moves through the hose

Principle of Operation

The calculator uses the following formulas:

Flow Rate (GPM) = C × √ΔP

Where C is the flow coefficient and ΔP is the pressure drop. This formula is based on the principles of fluid dynamics and assumes water at 60°F (15.5°C).

Practical Applications

This calculator can help you:

  • Design irrigation systems
  • Size fire hoses for emergency applications
  • Plan water distribution systems in industrial settings
  • Ensure adequate water supply for agricultural equipment

Note: For more complex applications, consider factors like hose material, temperature effects, and friction losses not included in this simplified model.
