To function properly, a water outflow pipe must drop 1 inch for every 22 inches of horizontal distance.

a. Calculate the slope for this drain pipe.

b. A rainwater pipe 30 feet long must run under the edge of a roof. What is the minimum vertical distance the pipe must drop between its ends?

c. A design calls for a drainage pipe to cross a building 45 feet wide as it drops 25 inches. Is this pip steep enough to function properly? Explain.

a. Calculate the slope for this drain pipe.

1/22

b. A rainwater pipe 30 feet long must run under the edge of a roof. What is the minimum vertical distance the pipe must drop between its ends?

Turn 30 feet to inches so 30 * 12 = 360 inches

Now times 1/22 x 360 = 16.32 inches. If they want it in feet just change 16.32 to feet by dividing 16.32 / 12

c. A design calls for a drainage pipe to cross a building 45 feet wide as it drops 25 inches. Is this pip steep enough to function properly? Explain.

Change 45 feet to inches so 45 * 12 = 540

Now times 540 * 1/22 = 24.54 inches so 25 inches would be steep enough since it droops 25 inches.
