Hello student, to solve the given question, let us first write the relation for nussle number that is equal to hx divided by k.
00:09
Now this relation can be further rearranged as hx equals nu multiply by k divided by x.
00:18
Now here plug in the value for the nassal number given in the statement, we get hx equals 0 .035 reynolds number raised to power 0 .8 p.
00:30
R raised to power 1 by 3 multiplied by k by x.
00:35
Now after putting the value for the reynolds number, this can be solved as hx equals a multiply by x raised to power minus 0 .2.
00:46
Now according to the question for x equals l, we can write the equation as hx equals a multiply by l raised to power minus 0 .2.
01:00
Mark it as equation number one.
01:02
Now next we need to find the heat transfer coefficient that is the average convection coefficient.
