Question from randy, a parent: trying to figure out percentage of slope lets say i have to run a pipe 80' at a 1% slope how much pitch is that? |
Randy,
1% as a decimal is 0.01 and hence the slope is 0.01. That means for a run of pipe of a certain length the rise must be 0.01 times the length. Thus for you example, since the length of the run is 80 feet which is 80 × 12 = 960 inches the rise must be 0.01 × 960 = 9.6 inches.
I hope that helps,
Harley
