In this question, we have to find out the total heat transfer for the process for 1 to 3 as shown in the figure.
00:09
As this figure is between t and s, where the t unit is degree centigrade, means this is temperature and s, which unit is kilojou per kelvin.
00:22
So as at first point, the first point is at s at 1 and temperature as 55.
00:34
And at point 2, the s is 3 and the t is 360.
00:46
While at third point the s is 2 and 3 is also at 360.
00:54
So now as this is for a reversible process, so the area under the process line is t s diagram is equal to the heat transfer during that process.
01:37
So then as we have to find the total heat transfer for process of q 1 to 3 as first of all 1 goes to 2 so we as 1 to 2 we as 1 to 2 we transfer add then heat transfer from 2 to 3.
02:00
So this becomes as integral of 1 to 2 to t d s plus integral to 2 to 3.
