(Capacities in the table are based on the properties of commercial propane gas with a specific gravity of 1.52. Physical properties of the gas are based on those properties given in the Gas Processors Suppliers Association Engineering Data Book, Eleventh Edition) Notes: * Includes a 20% factor for fittings ** See Table 7.
