Question:

Consider a thin layer of liquid water on a concrete surface. The surrounding air is dry with a convection heat transfer coefficient of 50 W/m² . K. The liquid water has an emissivity of 0.95, and the air and surrounding temperature is 30°C. If the layer of liquid water has a uniform temperature of 20°C, determine the conduction heat flux through the concrete. Dry air a conv 9 cond 9rad devap Concrete T surr Thin layer of liquid water
