Heat Exchange Fins: Convection Calculator

Convection in Heat Exchange Fins Calculator

Heat transfer rate (q):

Convective heat transfer coefficient (h):

Perimeter of the fin cross-section (P):

Length increment along the fin(Δx):

Temperature of the fin at a given point (T):

Temperature of fluid (T_f):

How This Is Calculated

$$ q = h(P \Delta x)(T-T_f) $$ where:

q = Heat transfer rate (W)

h = Convective heat transfer coefficient (W/m²K)

P = Perimeter of the fin cross-section (m)

Δx = Length increment along the fin (m)

T = Temperature of the fin at a given point (K)

T_f = Temperature of fluid (K)

Assumptions

The system is in steady state.
Heat transfer is considered as being one-dimensional.
Surface temperature is uniform.
There is no change in phase.
