(193) 0-86M8-0-4, ) (1Q4) In drops (spheres) something similar takes place. The average increase in temperature, t, t, is found by multiplying the volume of the heated hollow sphere by its mean increase in temperature and dividing by the volume of the whole drop. The volume heated is equal to the section of the diagram of the heated hollow sphere multiplied by the surface of that sphere, which contains the centre of gravity of this diagram. ---g-= 0-215(9(8-2 x 0-2r, )V....

Columns 6-12 give, for sheets of water, jets and drops of 8 = 1-7 mm. thickness or diameter respectively, the mean increase in temperature of the whole mass in the times given, for each 1 difference in temperature. It is clearly seen from this Table 46 that the greatest transference of heat takes place at the moment of contact of water and steam, and that it then becomes much slower, since the difficulty experienced by the heat in entering the water increases with the depth. It is not maintained that this method of consideration, and the conclusions drawn therefrom, lead to infallible figures to be at once applied in construction. They appear, however, to approach very nearly to the truth and
