- Waves can interact in different ways with the medium.
Answer:
U = 11.67 W/m² °C
Explanation:
Inner diameter, d = 2.5 cm = 0.025 m
Thickness of the wall, t = 2 mm = 0.002 m
thus, the outer diameter, D = d + 2t = 0.025 + 2 x 0.002 = 0.029 m
Now, based on outside convection heat transfer
we have
on rearranging, we get
where, 
are the perimeter respective to inner and and outer diameter
on substituting the values, we get
or
U = 11.67 W/m² °C
