Short answers please. thanks

tl 12. In a retangle space shown below, the circulation of air is counterclockwise, which is caused by nature convection. The top and the bottom boundaries are heat-insulated. The temperatures of the other two boundaries are kept constant. Which boundary, the left or the right one, has the higher temperature? Why is that? q\"=0 T-constand T=constant g\" = 0

Solution

Answer 12.

1. Clockwise direction temperature is more than anticlockwise direction, because of air has to flow angainst gravitional and flow speed would be less. So, Air will be in contact for more time when it flows in right side of wall and temperature will be rise due to high contact time.
