Water Calculations |
|
To find the capacity of a pipe or cylinder in gallons, multiply the square of the diameter in inches by the length in inches and by 0.0034. |
|
To find the pressure in pounds per square inch of a column of water, multiply the height of the column in feet by 0.434. |
|
Doubling the diameter of a pipe increases its capacity four times. |
|
The gallons per minute which a pipe will deliver equals 0.0406 times the square of the diameter in inches, multiplied by the velocity of water in feet per minute. |
|
The weight of water (in pounds) in any length pipe is obtained by multiplying the length in feet by the square of the diameter in inches, and by 0.34. |
