Gas Line Sizing
Gas line Sizing 47. Chapter 4. Gas line Sizing We now know the kind of piping which can be used for the distribution of natural gas within a building and the rules for installation. Now we will learn how to size the pipe running to each appliance so that the proper amount of gas can be delivered to each piece of equipment, including adjustments required due to elevation. Some Important Assumptions have expanded to more than one cubic foot Before we jump into the process of due to the decrease in pressure of the air calculating the correct pipe size for a given surrounding the balloon. At 8,600 feet, the situation, we need to make a series of air pressure has dropped to 11 PSI, or only important assumptions. First, if you look 75% of the pressure at sea level. As a up the heat content of natural gas you'll result the balloon would have expanded by find a range of values from 1,000 BTUs per 25% up to cubic feet. If we then cubic foot to around 1,070 BTUs per cubic remove exactly one cubic foot of gas from foot.

Plug in these 755 BTU/ft3 = 263.58 CFH. Now look up this value on the 70 foot line of the table. The minimum pipe size capable of carrying 263.58 CFH is a 1 ¼” pipe.
