Question

A cooling tower is designed to transfer thermal energy away from a power station. Thermal energy from the power station warms the air inside the cooling tower.Air enters through holes at the bottom of the cooling tower and leaves through the top. Explain why the air moves as shown by the arrows.

Answer 1

The air moves accordingly due to the change in the the density and the convection

Explanation:

• The cool air enters the the tower from the bottom of the tower. However as it moves up the  tower there is heating up of the air.

• There is a decrease in the the air density when it is heated. as a result of this ,less denser substance moves UP.

• Due to constant heating of the air , expansion of the air and decrease in density takes place  because of which the constant upward movement of the air is continued.
