WebMay 13, 2024 · cp - cv = R. and we define the ratio of specific heats to be a number which we will call "gamma". gamma = cp / cv. If we divide the first equation by cp, and use the definition of "gamma" we obtain: R / cp = 1 - (1 / gamma) = (gamma - 1) / gamma. Now we use the equation we have derived for the entropy of a gas :

The coefficient of variation (CV) is defined as the ratio of the standard deviation to the mean , It shows the extent of variability in relation to the mean of the population. The coefficient of variation should be computed only for data measured on scales that have a meaningful zero (ratio scale) and hence allow relative comparison of two measurements (i.e., division of one measurement by the other).
