WebSG = specific gravity of natural gas 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 1000 BTUs 1 CFH = 1 MBH The specific gravity of natural gas varies from 0.55 to 1.0. Typical values are in the range 0.6 - 0.7. WebPer the Copper Tube Handbook (www.copper.org), once the fluid temperature exceeds 140°F, the velocity needs to slow down to 2 to 3 fps, as the water becomes more aggressive the hotter it becomes. To slow the velocity of water in a given pipe, either (a) the flow rate must reduce or (b) the pipe must get larger. cheap minilite wheels
