In this question, we need to draw the thermal circuit or the heat transfer for heat transfer or heat transfer through a plane, through a plane wall exposed to convents on both side, on both side where t1 is greater than t2.
00:58
So this is a plate and this is t1, this is t2, this is the length of the plate given and h1, t1 and h2, t2.
01:29
So these are the temperature given as, now considering the rate of heat transfer through the plane, the rate of heat transfer through the plane can be obtained from a relation that will be q is equals to to q is equal to t1 minus t1 upon 1 upon h1a which is equal to t1 minus t2 upon l which is length upon ka which is equal to t2 minus t1 upon 1 upon h2a.
03:10
After solving this or combining this we get t1 minus t2 upon 1 upon h1a plus l upon ka a plus 1 upon h2a.
03:42
So here the, so here convective heat transfer, heat transfer coefficient, coefficient on the left side of the, left side of the wall which is h1 and same as the coefficient of heat transfer on right wall which is h2.

Thickness of the wall is given as l which is thickness of wall which is l...
