Finally, select the size of the pipe using Figure 4.

Alternatively the pipe size can be calculated arithmetically. �ViF��C���Է��; 9O}L8%W�{TI3(����Զ�t� stream Steam is a compressible gas where the capacity of a pipe line depends on the size of the pipe and the steam pressure. Steam is a compressible gas where pipe line mass flow capacity depends on steam pressure. Sizing Steam Pipes . Information required to calculate the required pipe size: Example 10.2.4. However, for the pipe sizes, NPS 14 and above Outside Diameter is the same as NPS.
