...a rate of 33000 foot-pounds per minute in terms of the kilogram-metre and hour. 21. [A pound-degree is the amount of heat necessary to raise a pound of water through I degree Fahrenheit ; kilogram-degree is similarly understood, the degree, however, being centigrade.]...

...collision with the earth. The same effect would be produced by 772 pounds falling one foot. Conversely, the amount of heat necessary to raise a pound of water 1° would, if it could be all utilized, be capable of raising a pound weight 772 feet high, or 772 pounds...

...tell those of you who have read the previous lectures that a "heat unit" or "British Thermal Unit" is the amount of heat necessary to raise a pound of water one degree. In the column marked "Heat of Vaporization" is given the ' 'latent heat' ' or the number...

...pound of average Indiana coal yields 12,382 BTU One cubic foot of natural gas yields 1,104 BTU One British thermal unit (BTU) is the amount of heat necessary to raise one pound of water one degree Fahrenheit in temperature. Theoretically, therefore, one pound of Pittsburg...

...water at 62°. The volume of a pound of dry steam represented by the letter s varies with the pressure. The British Thermal Unit, BTU, is the amount of heat necessary to raise one pound of water from 62° F. to 63° F. The heat of the liquid is the amount of heat expressed in...

...degree in temperature. Taking a pound as the unit of mass and using the Fahrenheit thermometric scale, the amount of heat necessary to raise a pound of water 1° F. is equivalent to 778.5 foot-pounds of work. In the metric system the heat necessary to raise a gram...
