Estimate the heat loss by natural convection from the surface of a thin vertical plate that is maintained at a temperature of 1250°C. The dimensions of the plate is 0.5 m x 100 mm. The plate is exposed to still ambient air temperature of 25°C. From experiments, it is observed that the correlation Nu =(GrPr) 0.33 hold for all types of flow behavior. The properties of air at the mean temperature are: Density 1.015 kg/m³ Viscosity 2.086x10-5 kg/m s Specific heat 999.96 J/kg K Thermal conductivity 30.1 x 10-³ W/m K Coefficient if thermal expansion 2.87 x10-³ K-1 Estimate the heat loss by natural convection from the surface of a thin vertical plate that is maintained at a temperature of 1250°C.
