To quickly assess the difficulty of the text, read a short excerpt:
The rise of temperature from B to C is uniform, but the portion of the curve CD, although small, is not negligible compared with BC, fig- ure 11. Then, since the rate of ex- change during the interval CD is practically r 2, the temperature would have risen to C' had the equalization of heat from C to D been instantaneous, where C" is the intercept of DE ex- tended back to the ordinate through C. Call this temperature /' 2 . The cooling correction for the interval BC is that already deduced unde...r Special Case I. Hence the corrected rise of temperature will be t _ y JJI /-/ /) \ 2 6 1 "2 ^ 2 ly ^ (4) the abscissa of where 0^ is the time corresponding to ' 2? the point C or C f '. Special Case III. The rise of temperature . During the oper- ation is uniform, and the initial temperature is so adjusted that r 2 = 0, i. E. , DE is horizontal. This is evidently a special case of the above, and the corrected rise of temperature is t 2 ti y (0 ^ (5) Special Case IV. When the equalization of temperature CD is slow, as in c, figure 1, or constitutes a considerable por- tion of the total rise, it is advantageous to so adjust the initial temperature that the final temperature / 2 coincides as nearly as may be with the temperature of the surroundings, i.
