...(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...

...compression ; and let P, V, and T be what they become when the compression is concluded. Then if k denote the ratio of the specific heat of air at constant pressure to the specific heat of air kept in a space of constant volume, and if, as appears to be nearly, if not...

...account, was 916 feet a second. Laplace proved that by multiplying Newton's velocity by the square root of the ratio of the specific heat of air at constant pressure, to its specific heat at constant volume, the actual or observed velocity is obtained. Conversely, from a comparison of the calculated and observed...

...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. How will you do it ? s. Sketch an experimental...

...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 of this ratio for air and other permanent...

...elastic, or less elastic, in a greater degree than is given by Boyle's law. Taking /3 to represent the ratio of the specific heat of air at constant pressure to the specific heat at constant volume, If then a small portion of fluid, the density of which is pv...

...and the specific heat of air at constant volume is therefore 11724 x 64 90x5 From this we see that the ratio of the specific heat of air at constant pressure to its specific heat at constant •237 volume is — -*-'-- = T42... According to the best experiments the value of this ratio for...
