Demonstrating How to Calculate the Required Hose Length and Diameter

Calculating the required hose length and diameter ensures optimal flow and minimizes pressure drop, which can affect the efficiency of your operations.

Calculating Hose Length: Determine the total distance the fluid must travel, including the distance between the source and destination, and any bends or curves in the routing. Add extra length for flexibility and ease of installation.
Calculating Hose Diameter: The hose diameter affects the flow rate and pressure drop.

Flow Rate (GPM) = Velocity (ft/s)
– Area (ft²)
– 7.48 (gal/ft³)

Use the following formula:
- Flow Rate: Determine the required flow rate in gallons per minute (GPM) or liters per minute (LPM).
- Fluid Velocity: Choose an appropriate fluid velocity. Higher velocities can lead to increased pressure drop and potential erosion, while lower velocities may require larger hose diameters. A common range for water is 4-8 ft/s.
- Area: Calculate the cross-sectional area of the hose using the formula:
  
  Area = π
  – (Diameter/2)²
  
  Rearrange the flow rate formula to solve for the area, and then solve for the diameter.
  For example, consider a system that requires a flow rate of 50 GPM and a fluid velocity of 6 ft/s.
- Area Calculation: Area = Flow Rate / (Velocity
  – 7.48) = 50 GPM / (6 ft/s
  – 7.48 gal/ft³) ≈ 1.11 ft²
- Diameter Calculation: Diameter = 2
  – √(Area / π) = 2
  – √(1.11 ft² / π) ≈ 1.19 ft or approximately 14 inches. In this case, you might choose a hose with a 14-inch diameter or the closest available size.
