Condensation on Inclined Surfaces

Nusselt’s analysis for film condensation on inclined surfaces resulted the following expression for heat transfer coefficient: \[h_m = 0.943\left[\frac{g\rho(\rho-\rho_v)\lambda k^3}{\mu (T_v-T_w)L} \sin\phi \right]^{1/4} \tag*{(42)}\] where \(\phi\) is the angle of inclination of the plate to the horizontal plane.
