...— " The velocity of sound, is equal to the product of the velocity given by the formula of Newton, by the square root of the ratio of the specific heat of air under a constant pressure, to its specific heat under a constant volume." The theory of Laplace applied...

..." The actual velocity of sound is equal to the velocity given by the formula of Newton, multiplied by the square root of the ratio of the specific heat of air under a constant pressure, to its speci6c heat under a constant volume." The first of these specific...

...sound should be obtained by multiplying the velocity calculated, according to the formula of Newton, by the square root of the ratio of the specific heat of air under a constant pressure, to the specific heat of the same fluid under a constant volume. M. Poisson...

...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...

...(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 of heat ; finally, we found Mr....

...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...
