The heat transfer rate due to free convection from a vertical surface, 1 m high and 0.6 m wide, to quiescent air that is 30 K colder than the surface is known. What is the ratio of the heat transfer rate (i. e. q1/q2) for that situation to the rate corresponding to a vertical surface, 0.6 m high and 1 m wide, when the quiescent air is 30 K warmer than the surface?
