Web2 aug. 2024 · The convection coefficient h (W/m 2 K) appears in the heat transfer equation q ˙ = h A Δ T where q ˙ is the heat flow (W), A is the area (m 2 ), and Δ T is the temperature difference (K or o C). The coefficient h expresses how effective a fluid is at transporting heat in the presence of mass flow. Consider each of your conjectures.
WebHEAT TRANSFER THROUGH A WALL. Heat transfer by conduction through walls follows the basic relation given by Fourier’s equation in which the rate of heat flow, Q, is proportional to the temperature gradient, dT/dx, and to the area normal to the heat flow, A.
