# Convection heat-transfer data are often reported as a heat-transfer coefficient h, defined by Q = hAT Where

## Question:

Q = hAΔT

Where Q = heat flow, J/s

A = surface area, m2

ΔT = temperature difference, K

The dimensionless form of h, called the Stanton number, is a combination of h, fluid density ρ, specific heat cp, and flow velocity V. Derive the Stanton number if it is proportional to h.
