If a 50 foot pipe needs a 2 percent grade what is the difference in elevation?

2% grade is equal to 1/4" per foot or 1:50(metric)
If you know the length and the grade and need the total fall:
TF=l x g
:. TF = 50' x 1/4"per foot (or 0.25)
TF = 12.5" or 12'-6"
To find the grade:
g = TF / l
To find the length:
l = TF / g
