Here I go through the two examples of a throttle and a heat exchanger. I look at the energy equation, and solve that. Then I look at the rate of entropy production. It is positive in both cases…

Here I show some reversible processes and show that they cannot be really created. This shows the cause of entropy. FRICTION!
