...metal rod and in air, to determine the pressure of the atmosphere and its density, and to calculate the ratio of the specific heat of air at constant pressure to that at constant volume. Water in pressure tubes (cm.) Theoretical discharge (cu. cm. per sec.) Q Volume...

...Maxwell's value deduced from Stefan's measurements,1 D=0-198 Londolt and Bornstein's Tables, 7 = 1-41 the ratio of the specific heat of air at constant pressure to that at constant volume, B, =0-2375 and substitute in the formula (3*), we have Thus under the conditions...

...Standard efficiency volume of gas before compression R = volume of gas after compression r = Ratio of specific heat of air at constant pressure to its specific heat at constant volume: ie 1.408. (Assumed constant for all temperatures, but, actually, this is only approximately true.)...

...during the passage of a sound- wave, Xewton's formula should be corrected to V = KB T5" where К is the ratio of the specific heat of air at constant pressure to that at constant volume. Now it can be proved that in any elastic body the velocity of wave-propagation...

...clearance or valve losses, the values of the other symbols being as before, then y in the above equation is the ratio of the specific heat of air at constant pressure to its specific heat at constant volume = 1-408. Substituting this figure for y, V fn \°'20 U' = 3-451 The work (U') done in adiabatic compression...

...adiabatic curves could be calculated on the dynamical theory from the ratio now usually designated 7, of the specific heat of air at constant pressure to its specific heat at constant volume. On similar reasoning it was shown later that the value of pv y is constant at every point on the curve....
