The variation for a 100 cubic foot cylinder at various temperatures is given in the following tabulation: At 150 Fahr........................ 2090 pounds. At 100 Fahr........................ 1912 pounds. At 80 Fahr........................ 1844 pounds. At 68 Fahr........................ 1800 pounds. At 50 Fahr........................ 1736 pounds. At 32 Fahr........................ 1672 pounds. |
