Explanation:
The given data is as follows.
, 
Area of the flat plate is 2 × 4 = 8
.
Average convection heat transfer coefficient
=
=
.
Hence, formula to calculate heat transfer through convection from air to the water is given as follows.
q = 
=
= 24000 W
or, = 24 kW
Hence, the direction of heat flow is from air to the surface.
Thus, we can conclude that transfer of heat is 24 kW.
Answer:
The critical chemical difference is that CO2 contains one atom of carbon and two atoms of oxygen, whilst CO has one carbon and one oxygen atom.
