question

Compute the rate of heat transfer by natural convection from thesurface of a horizontal, 7 in. square, plate at a temperatureof 300°F. The ambient air temperature is 80°F. EMPIRICAL EQUATIONS FOR NATURAL CONVECTION FROM HORIZONTAL PLATES TO ROOM TEMPERATURE AIR AT ATMOSPMERIC PRESSURE Configuration Equation Turbulent Region Range of X 2 × 10^7 - 3 × 10^10 Laminar Region Range of X 10^5 - 2 × 10^7 Heated horizontal plates facing upward h = 0.22\Deltat^1/3 h = 0.27(\Deltat/ L)^1/4 Hasted horizontal plates facing downward ... h = 0.12(\Deltat/ L)^1/4 Cooled horizontal plates facing upward ... h = 0.12(\Deltat/ L)^1/4 Cooled horizontal plates facing upward h = 0.22\Deltat^1/3 h = 0.27(\Deltat/ L)^1/4
