To function properly a rainwater outflow pipe must drop exactly 1 inch for every 25 inches of horizontal distance . A design cal
ls for a drainage pipe to drop 25 inches as it crosses a building 45 feet wide.will the drainage pipe function properly? a)The pipe does not drop enough vertically to function properly.
b)The pipe drops too much vertically to function properly.
c)The pipe will function properly.
d)There is not enough information to determine if the pipe will function properly.
B, the pipe drops too much vertically to function properly.
We start off knowing the horizontal distance, 45 feet. We multiply that by 12 to convert it to inches, and we get 540. Now, we divide 540 by 25 to find out how many inches the pipe needs to drop. Turns out, 540/25 is 21.6, so 25 isn’t the exact inches we need it to drop. It drops too much.
