WebPiping systems in residential buildings are traditionally operated at 8-inch water column (WC) or 1/3 PSIG. By raising the pressure to 2 PSIG, several benefits become available when constructing residential dwelling units where the distance from the meter to the first appliance is great. WebThis pressure will be about 5-inch water column (w.c.) (1.25 kPa), ... Capacities for gas at pressures 2.0 psig (13.8 kPa) or greater in cubic feet per hour of 0.60 specific gravity gas for different sizes and lengths are shown in Tables 402.4(5) through 402.4(7) for iron pipe or equivalent rigid pipe; Tables 402.4(12) to 402.4(14) for ... how to screenshot on keyboard

WebDownload Natural Gas Pipe Capacity Chart as pdf-file pressure less than 1 1/2 psig common to use fittings factor 1.5- equivalent pipe length in table above = pipe length + 50% pressure drop 0.5 inches water column specific gravity of natural gas 0.6 One MBH is equivalent to1000 BTU's per hour (0.29 kW = 0.29 kJ/s) WebConvert the 3.5-psi pressure gauge reading to inches-of-water (inH2O) pressure. Since 27.71 inches of water height equals 1 psi, then the pressure is 3.5 psi x 27.71-inH2O/psi = 96.985 inH2O. Step 4 Calculate the actual tank level by dividing the net head pressure by specific gravity. Substituting values, 96.985 inH2O/1.02 SG = 95.08 inches.
