How to calculate water in a pipeline?

To calculate the volume of water in a pipeline, you need to determine the volume of the pipe and convert it to gallons. Here's how:

Steps to Calculate Water Volume in a Pipeline

1. Determine the Pipe's Dimensions: You'll need the pipe's length and radius (or diameter). Ensure all measurements are in the same units (e.g., feet).

2. Calculate the Volume in Cubic Feet: Use the formula for the volume of a cylinder:

   • Volume = π r² l
   • Where:
     • π (pi) ≈ 3.14159
     • r = radius of the pipe
     • l = length of the pipe

3. Convert Cubic Feet to Gallons: Multiply the volume in cubic feet by 7.48 to get the volume in gallons. According to the provided reference, the formula uses the conversion factor 7.48 gallons per cubic foot.

   • Volume (in gallons) = Volume (in cubic feet) * 7.48

Example

Let's say you have a pipe that is 100 feet long with a radius of 0.5 feet.

1. Volume (in cubic feet) = 3.14159 (0.5)² 100 = 78.54 cubic feet

2. Volume (in gallons) = 78.54 * 7.48 = 587.43 gallons

Therefore, the pipe contains approximately 587.43 gallons of water.
