QUESTION:
For the silicon chip of Example 2.5, determine the rate of entropy production, in kW/K. What is the cause of entropy production in this case?
ANSWER:Solution 54P:
Step 1 of 2:-
Here we need to find the rate of entropy production and the cause of it for example 2.5.
The electrical power input is given as,
The temperature of the chip we have found in example 2.5 is: .
From entropy balance we know that,
But for steady state, the rate of change of entropy is zero.
So, the term will become,
So, the rate of entropy production is:
