Page 150 - Instruction-plate on the battery, all cells are gassing (bubbling) freely and evenly and the gravity of all cells has shown no further rise during one hour. The gravity of the solution in cells fully charged as above Is 1,275 to 1,300.
Page 207 - A convenient unit of work is the "footpound", which is the work done in lifting a weight of one pound...
Page 52 - It is related directly and simply to the " erg," which is the unit of work of the centimetregramme-second system. Reference has already been made to the fact that when a current of electricity is passed through a conductor heat is generated, the amount depending on the resistance of the conductor and the strength of the current. This heat is the equivalent of the energy electrically expended. The joule is the energy expended in one second by a current of one ampere passing through a resistance of...
Page 365 - Boyle's Law of Gases: A law defining the volume and pressure of gases at constantly maintained temperatures. It states that the volume of a gas varies inversely as the pressure so long as the temperature remains the same ; or, the pressure of a gas is proportional to its density.
Page 214 - ... is the effect of the clearance volume (ie, the volume occupied by the refrigerant within the compressor that is not displaced by the moving member). This effect is illustrated in the case of the...

Steam, Cycle of: A series of operations of steam forming a closed circuit, a fresh series) beginning where another ends; that is, steam is generated in the boilers, passes through the pipes of the engine, doing work successively in its various cylinders, escaping at exhaust pressure to the condenser, where it is converted into water and returned to the boiler...
Page 206 - ... from its original temperature to the temperature of the steam is then immediately known, if we take, as the unit of heat, the quantity of heat that is given out by a pound of steam in condensing into a pound of water at the same temperature. Bomb Calorimeter. Another and more familiar unit of heat is the quantity of heat required to change the temperature of a given weight of water 1 on a given thermometer scale. Thus in general engineering practice in the United States and England it is customary...
