Consider a 1 cm thick copper wall (k=375 W/m K) whose one surface is exposed to condensing water vapor (h=10000 W/m² K) at a temperature of 200°C . The other surface is in contact with ambient air (h= 5 W/m²K) at a temperature of 25°C. a) Calculate the heat per unit area across the plate. b) Determine the temperatures at both surfaces of the wall.
