 Question from peter: a sewer ditches to be 148 feet long. the pipe is installed with a 2% grade. what would be total amount of fall be?

Hi Peter,

The fact that the pipe is installed with a 2% grade means that the drop is 2% of the length. The length is 148 feet so the drop is 2% of 148 feet or $0.02 \times 148 = 2.96$ feet.
