Schedule number of a pipe, which is a measure of its wall thickness, is given by ________________?
Correct answer: A. 1000 P'/S
- A. 1000 P'/S
- B. 100 P'/S
- C. 1000 S/P'
- D. 10000 P'/S
Explanation
The pipe schedule number is commonly calculated as 1000 times the design pressure divided by the allowable stress, or 1000P′/S. A higher pressure or lower allowable stress therefore requires a thicker wall.
