Question: The heat-transfer rate per unit area q to a body from a fluid in natural or gravitational convection is a function of the temperature difference

The heat-transfer rate per unit area q to a body from a fluid in natural or gravitational convection is a function of the temperature difference ΔT, gravity g, body length L, and three fluid properties: kinematic viscosity ν, conductivity k, and thermal expansion coefficient β. Rewrite in dimensionless form if it is known that g and β appear only as the product gβ.
