Question

When calculating what size pipe to use for a specific flow requirement, we always use the standard size up to the calculated size needed. Which of the statements below explain why? Check all that apply.

Smaller pipe sizes are more fragile

Smaller pipe sizes are more difficult to manufacture

Using the next standards size down would necessitate a greater slope to meet the same flow capacity

Using the next standards size down would necessitate a greater slope to meet the same velocity

Using the next standards size down would necessitate a greater slope to meet the same velocity

Explanation / Answer

Using the next standards size down would necessitate a greater slope to meet the same flow capacity. This is because if we use size down then it will give less pressure at the end and thus flow capacity would be reduced.
