): The product of the Grashof and Prandtl numbers. It determines whether the flow is laminar or turbulent. Nusselt Number (

), which is the average of the surface and ambient temperatures: ): The product of the Grashof and Prandtl numbers

In this chapter, the solution manual covers the physics of buoyancy-driven flows and the empirical correlations used to calculate heat transfer rates for various geometries. Unlike forced convection, which uses the Reynolds number ( ), natural convection relies on the ( ) to determine the flow regime. Core Concepts & Governing Equations ): The product of the Grashof and Prandtl numbers
