The capacity of a low pressure natural gas (less than 1 psi) pipe line can be calculated with the Spitzglass formula like

q = 3550 k ( h / l SG)1/2

(1)

where

q = natural gas flow capacity (cfh) h = pressure drop (in Water Column)

l = length of pipe (ft) k = [d 5 /(1 + 3.6/d + 0.03 d)] 1/2

d = inside diameter pipe (in) SG = specific gravity

For natural gas the nominal BTU/cf varies from about 900 to 1100 BTU/cf . In general it is common to set

1 Cubic Foot (CF) = approx 1,000 BTUs

1 CFH = 1 MBH

The specific gravity of natural gas varies from 0.55 to 1.0 .

The downstream pressure in a houseline after the meter/regulator is in general in the

range of 7 to 11 inches Water Column, or about 1/4 psi.

Example - Natural Gas Pipe Capacity

The capacity of a 100 ft natural gas pipe with a nominal diameter 0.5 inches (actual ID 0.622 in )

and 0.5 inches WC pressure drop can be calculated as

k = [(0.622 in)5

/(1 + 3.6 / (0.622 in) + 0.03 (0.622 in))]0.117

q = 3550 0.117 ( (0.5 in) / (100 ft) 0.60 ) 1/2 = 37.9 cfh

Specific gravity of natural gas is set to 0.60 .
