A square flat plate is 1.5 m by 1.5 m. Its two surfaces are maintained at 120 C. The plate convects from its two surfaces to the room air which is at 20 C. (a) What is the rate of heat transfer to the air if the plate is vertical? (b) What is the rate of heat transfer to the air if the plate is inclined 45° with the horizontal?
