Oh, dude, a 1 in 40 fall on a drainage pipe means that for every 40 units of horizontal distance, the pipe will drop by 1 unit vertically. It's like the pipe is playing a little game of "let's go downhill slowly" as it carries all that water away. So yeah, it's just a fancy way of saying the pipe is sloping down to help with the drainage.

BlakeA "1 in 40 fall" on a drainage pipe refers to the slope or gradient of the pipe. It means that for every 40 units of horizontal distance, the pipe drops by 1 unit vertically. This slope is typically expressed as a percentage, in this case, it would be a 2.5% slope. This slope is important for ensuring proper drainage flow and preventing blockages in the pipe.
It generally refers to a ratio of the 'fall' in drainage from the insert or 'inlet' to the 'outlet' calculated byusing fall = ratio X distance
1:40 would be 1/40 = 0.025 - assume a 3 meter distance for eg sake.
fall = 0.025 X 3
fall = 0.075 or 75mm from the inlet to the outlet.

If you mean: 40+(40*0)+1 = 41
How many gallons of water does a 16 pipe hold per foot?
16" pipe per foot = 9.17 Gallons for 16" SCH 40 pipe we just had to figure it out in our engineering department was looking for a short cut and ran across your post.
72 is 40 percent of what number?
72 divided by 40 is 1% so 100 times that is...
What is 40 percent off 43.20?
If you mean 40% of 43.20, the 0.40 x 43.20 = 17.28. If you mean 40% off of 43.20, then subtract the 17.28 from 43.20 to get 25.92
