Formula Derivation for Gallons per Foot of Pipe
The formula calculates gallons per foot by multiplying the pipe’s volume in cubic inches per foot by the conversion factor (1 gallon = 231 cubic inches), ensuring precise measurements for system design and fluid dynamics applications.
Mathematical Formula Explanation
The formula to calculate gallons per foot of pipe is derived from basic geometric principles. It involves determining the cross-sectional area of the pipe and then multiplying by its length. The formula is:
Gallons per Foot = (π × (Diameter/2)² × 12) / 231. Here, π is a constant (~3.14159), and the diameter is halved to find the radius. Squaring the radius gives the area in square inches. Multiplying by 12 converts inches to feet, and dividing by 231 (cubic inches per gallon) converts the volume to gallons.
