Then if k denote the ratio of the specific heat of air at constant...if, as appears to be nearly, if not rigorously true, A be constant for varying temperatures and pressures, we shall have by the investigation in Miller's...

...(T-0)(rl)MKv (I) In which T is the temperature of the air in the working cylinder, 6, that of the weather, y, the ratio of the specific heat of air at constant pressure to that at constant volume, M the mass of air heated ; and Kv, the symbol employed by Mr. Rankine to express...

...sound in atmospheric air. We found Laplace, by a special assumption, deducing from these velocities the ratio of the specific heat of air at constant pressure, to its specific heat at constant volume. We found Mayer calculating from this ratio the mechanical equivalent...

...and V the temperature from absolute zero, pressure, and volume of air after compression ; and k is the ratio of the specific heat of air at constant pressure to that at constant volume. Professor W. Thomson has deduced, as a consequence of the above, the following...

...determined ? In what order do the higher rates of vibration of a tuning fork follow each other ? r. From the ratio of the specific heat of air at constant pressure to its specific heat at constant volume you are required to deduce the mechanical equivalent of heat....

...the mechanical equivalent of heat as 1,390 foot-pounds? (31.) Determine from the following experiment the ratio of the specific heat of air at constant pressure to that of air at constant volume, and deduce from this ratio the mechanical equivalent of heat : A definite...

...air at constant volume is therefore 1-1724x64 „ —j^—;— = 1667... 90 xo From this we see that the ratio of the specific heat of air at constant pressure to its specific heat at constant volume is ' .'" = 1-42... According to the best experiments the value...
