The formula for the rate of heat loss (H) in terms of speed (V), area (A), and density (ρ) is given by:
H = 0.5 * ρ * V^3 * A
In this equation, the rate of heat loss (H) is proportional to the density of the fluid (ρ), the cube of the velocity (V^3), and the surface area (A) through which the heat is being lost. The factor of 0.5 represents a coefficient that depends on the specific context and assumptions of the problem, such as the shape and orientation of the object experiencing heat loss.
It's important to note that this formula assumes that the heat loss is due to convective heat transfer, which is applicable in situations where a fluid (such as air or a liquid) is in contact with the surface from which heat is being lost. The formula may not be directly applicable to other modes of heat transfer, such as conduction or radiation.
