Answer:
Detailed step wise solution is given below:
Consider two flat plate airfoils as lumped "lifting elements" in a tandem arrangement, where the second airfoil is located at so
me distance downstream from the first airfoil. The chords and attack angles of both airfoils are the same. Find the circulations of these airfoils in terms of the free-stream velocity U , attack angle , chord c , and the distance between the airfoils’ leading edges d . Which airfoil generates higher lift force and why? Discuss the effect of the distance between the airfoils on their aerodynamic interaction.

Answer:
a. Heat removal rate will increase
b. Heat removal rate will decrease
Explanation:
Given that
One end of rod is connected to the furnace and rod is long.So this rod can be treated as infinite long fin.
We know that heat transfer in fin given as follows
We know that area
Now when diameter will triples then :
So the new heat transfer will increase by 3 times.
Now when copper rod will replace by aluminium rod :
As we know that thermal conductivity(K) of Aluminium is low as compare to Copper .It means that heat transfer will decreases.
