If you have six long radius 90° elbows for an 8" pipe, what is the take-off?

To determine the take-off for six long radius 90° elbows on an 8" pipe, it's essential to understand what "take-off" refers to in piping design. Take-off is the total length of pipe that is added to accommodate the fittings, which includes the additional length introduced by the elbows.

For long radius elbows, the take-off is generally calculated using a standard formula. The take-off distance for a long radius 90° elbow is typically 1.5 times the diameter of the pipe. In this case, for an 8" pipe, the calculation for one long radius elbow would be:

Take-off for one elbow = 1.5 x 8" = 12".

Since you have six elbows, you'll need to multiply this value by the number of elbows:

Total take-off = 12" x 6 = 72".

However, the question is asking for the take-off distance of one elbow in relation to the options given. Since the take-off of one long radius 90° elbow on an 8" pipe is 12", this matches the provided correct answer.

Thus, the correct choice reflects the understanding of how to calculate the additional length needed for the fittings, ensuring accurate pipe layout and assembly
