Answer:
- Fins should be attached outside the tube
- Fins can be attached on both sides when convection coefficient of air inside the tube is equal to the convection coefficient of atmospheric air outside the tube
Explanation:
The main function of the fins that are to be added is to ensure the speedy transfer of heat from the Hot air.
The fins should be attached outside the tube because the convection coefficient of air is higher inside the tube than the convection coefficient of the outside air ( atmospheric air ), BUT
When convection coefficient of air inside the tube is equal to the atmospheric air outside the tube, it is recommended that the fins can be added on both sides of the tube ( i.e. in and outside the tube )
Maybe because of shipping costs and if you need to buy materials from a far place such as different international travels?

Answer:
Weight of block is 191.424 Kg
Explanation:
The volume of rectangular block = cubic meter
1/5th of its volume being out of water which means water of volume nearly 4/5 th of the volume of rectangular block is replaced
Volume of replaced water = cubic meter
Weight of replaced water = weight of rectangular block = Kg/M3
= 191.424 Kg
