Seite 18 - In defining the unit of heat it is necessary to specify the temperature of the water because the amount of heat necessary to raise the temperature of one pound of water through one degree varies slightly at different temperatures.
Seite 73 - Ib. per square inch, is as low as is necessary. The concentration of the acid is effected in a lead-lined vessel, in which is a coil of lead piping heated by steam, the pressure in the vessel being kept down by means of an ordinary air-pump. No acid pump is needed, as the transfer from one vessel to another is effected by the pressure of the atmosphere. The comparatively cool weak...
