Drive System Mechanical Formulas Formulas and Constants 1 hp = 33,000 / Foot-pounds of work per minute. 1 hp = .746 K.W. = K.W. 1.341. 1 hp = 2,547 B.T.U. per hour. 1 B.T.U. = Heat required to raise 1 lb. water 1 F. 1 B.T.U. = 777.6 / Foot-pounds work. 1 Kilowatt Hour = 3,415 B.T.U. Heat Value of Carbon = 14,600 B.T.U. per pound. Latent Heat of Fusion of Ice = 143.15 B.T.U per pound. Latent Heat of Evaporation of Water at 212 F. = 970.4 B.T.U. per pound. Total Heat of Saturated Steam at Atmospheric Pressure = 1,150.4 B.T.U. per pound. 1 Ton of Refrigeration = 288,000 B.T.U. per 24 hours. g = Acceleration of Gravity (commonly taken as 32.16 feet per second per second). 1 Radian = 57.296 degrees. 1 Meter = 100 cm. = 39.37 inches. 1 Kilometer = .62137 miles. 1 Gallon = 231 cubic inches. 1 Barrel = 42 gallons. Atmospheric Pressure = 14.7 pounds per sq. in. = 29.92 inches mercury at 32 F. 1 Lb. Per Sq. In. Pressure = 2.3095 feet fresh water at 62 F. = 2.0355 inches mercury at 32 F. = 2.0416 inches mercury at 62 F. Water Pressure (pounds per sq. in.) = .433 X height of water in feet (Fresh water at 62 F). Weight of 1 cu. ft. Fresh Water = 62.355 lbs. at 62 F. = 59.76 lbs. at 212 F. Weight of 1 cu. ft. Air at 14.7 lbs. per sq. in. Pressure = .07608 lbs. at 62 F = .08073 lbs. at 32 F.
