Natural gas regulating capacities at selected inlet pressures

and outlet pressure settings are given in Tables 2 and 3.

Flows are in SCFH (60°F and 14.7 psia) of 0.6 specic

gravity natural gas. To determine the equivalent capacities

for other gases, multiply the table capacity by the following

appropriate conversion factor: 0.775 for air, 0.789 for

nitrogen, 0.625 for propane, or 0.548 for butane. For gases

of other specic gravities, multiply the given capacity by

0.775, and divide by the square root of the appropriate

specic gravity.

Then, if capacity is desired in normal cubic meters per

hour (Nm

/h) at 0°C and 1,01325 bar, multiply SCFH

by 0.0268.
