Eq 2.34 – Convection Heat Transfer

Heat transfer rate due to the convection of a fluid passing over a surface

\(\displaystyle \dot{Q}_{\text{conv}} = h\,A\,(T_s - T_\infty)\)

Symbols

\(\dot{Q}_{\text{conv}}\) — heat transfer rate
\(h\) — convection heat transfer coefficient
\(A\) — area of the surface
\(T_s\) — temperature of the surface
\(T_\infty\) — temperature of the fluid, fixed at 300 K

Schematic

Inputs & Outputs

Surface area \(A\) (m²)

Surface temperature \(T_s\) (K)

\(T_\infty\) — fluid temperature (K) fixed at 300 K

Heat transfer rate \(\dot{Q}_{\text{conv}}\)

— kW
