The formula to calculate the Rayleigh Number (RN) is:
\[ \text{RN} = \text{GN} \times \text{PN} \]
Where:
The Rayleigh Number is a dimensionless number in fluid dynamics that characterizes the flow regime in natural convection. It is the product of the Grashof number (which measures the buoyancy force compared to viscous force in a fluid) and the Prandtl number (which measures the ratio of momentum diffusivity to thermal diffusivity). The Rayleigh Number indicates whether a fluid will be stable or whether it will undergo convection. Higher values typically indicate a greater tendency for the fluid to undergo convection.
Let's assume the following values:
Using the formula to calculate the Rayleigh Number:
\[ \text{RN} = 500,000 \times 0.71 = 355,000 \]
The Rayleigh Number is 355,000.
