WebMay 13, 2024 · Eq #2: a = sqrt (gam * p / r) = sqrt (gam * R * T) where R is the gas constant from the equations of state. If we begin with the entropy equations for a gas, it can be shown that the pressure and density of an isentropic flow are related as follows: Eq #3: p / r^gam = constant. The raw moments are given by: where is the gamma function. The mean of a Rayleigh random variable is thus : The standard deviation of a Rayleigh random variable is: The variance of a Rayleigh random variable is :
