...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... | |
