Fuel Oil—calorific values 18,500 to 21,100 B. T. U. per pound, increasing with
degrees Baume—Formula B. T. U.= 18,650 plus (40 x Baume0—10).
Work of one ordinary man for 10 hours.
4,500 pounds raised I foot per minute or 0.2 H. P. or 36 pounds at 4.8 feet
per minute—or 288 feet per hour—with single pulley.
100 ,000 pounds water per hour I foot in height.
2 calorie = 3.968 B. T. U.
Heat Unit (B. T. U.) quantity of heat required to raise I pound water i° Fah-
renheit at 39.20 Fahrenheit.
Specific heat (coefficient of thermal capacity) is the ratio of the heat required to
raise the temperature of a given substance one degree as compared with water.
Specific heat of oil is 0.4.
Latent heat—quantity of heat required to convert a body from a given state to
another state without changing its temperature, as ice to water (144 B. T. U.)
or water to steam (965.8 B. T. U.)
3 B. T. U. = 0.252 French calorie.
