                   Actual yield (P) of a water-gas installation is defined as the ratio R:R_o, where R is the ratio of the amount of heat obtainable from the gas produced to that produced by burning the C used, R_o is the theoretical maximum ratio, and P is calculated on various semiempirical assumptions for varying relative amounts of CO₂, H₂O and N₂.
