How to Use the Friction Loss Calculator

This guide will walk you through the process of using the Friction Loss Calculator to determine the friction loss and total pressure loss in a hose setup. Follow each step carefully to ensure accurate calculations.

Step 1: Enter the Flow Rate

Begin by providing the Flow Rate of the fluid through the hose. This value should be input in gallons per minute (GPM). Click on the input field labeled “Flow Rate (GPM)” and enter the value. Ensure that the number falls within the allowed range, which is 0 to 2000 GPM.

Step 2: Select the Hose Diameter

Next, select the Hose Diameter from the available options. Click on the dropdown menu labeled “Hose Diameter (inches)” and choose the appropriate diameter for your hose. The options range from 1.5 inches to 5 inches.

Step 3: Input the Hose Length

Proceed by entering the Hose Length in feet. Use the input field labeled “Hose Length (feet)” to type in the total length of the hose. Ensure that the length is within the valid range of 0 to 5000 feet.

Step 4: Choose the Coefficient C Value

Select the appropriate Coefficient C Value from the dropdown menu. This coefficient is essential for calculating friction loss and varies based on the type of hose. Choose from the provided options: Smooth Bore, Rubber Lined, or Rubber Covered, with respective values of 140, 120, and 100.

Step 5: Calculate the Results

After completing the input fields, the calculator will automatically compute the results based on the provided data.

  • Friction Loss (PSI): This represents the loss of pressure per 100 feet of hose. It is calculated using the given formula and is displayed in PSI.
  • Friction Loss per 100ft: This value shows the friction loss for every 100 feet of hose length, formatted as PSI/100ft for easy reference.
  • Total Pressure Loss: This combines the friction loss with a constant pressure factor related to the hose length to give the overall pressure loss in the system.

Each of these results is formatted to two decimal places and provided with the appropriate units for clarity.

Step 6: Review Your Results

Carefully review each of the calculated results to interpret and make decisions based on the friction loss and total pressure loss in your hose system. This information can help in assessing the efficiency and effectiveness of your fluid handling system.
