How many 1⁄2" stainless steel tracer lines can a 2" NPS header supply?

To determine how many 1⁄2" stainless steel tracer lines can be supplied by a 2" NPS header, we need to consider the pipe sizing and the equivalent flow capacity.

A 2" NPS (Nominal Pipe Size) header has a certain internal diameter, which is significantly larger than that of a 1⁄2" pipe. The internal diameter of a 2" pipe is approximately 2.067 inches, while a 1⁄2" pipe has an internal diameter of about 0.622 inches. This difference in diameter indicates that the larger header can supply multiple smaller pipes based on the flow area available.

When calculating the number of 1⁄2" tracer lines that can be accommodated by the 2" header, one can use the formula for the cross-sectional area of the pipes to determine how many smaller pipes can effectively be supplied by the larger pipe.

The cross-sectional area of the 2" pipe is much greater compared to that of the 1⁄2" pipe. A 2" pipe can be calculated to have an area sufficient to support approximately 16 half-inch pipes based on their respective flow areas.

Thus, the answer of 16 indicates that the
