WebA Rayleigh random variable, like the exponential random variable, has a one-sided PDF. The functional form of the PDF and CDF is given (for any σ > 0) by. (3.28a) (3.28b) Plots of these functions are shown in Figure 3.11. The Rayleigh distribution is described by a single parameter, σ2, which is related to the width of the Rayleigh PDF. This means the Rayleigh number is a type of Péclet number.For a volume of fluid of size in all three dimensions [clarification needed] and mass density difference , the force due to gravity is of the order , where is acceleration due to gravity.
