The relation between the reversible and irreversible QL

Answer to Problem 5.1P
Explanation of Solution
Given information:
Two engines receive the same heat transfer in (QH). One engine is reversible and other engine is irreversible.
Concept used:
The efficiency of reversible heat engine is more than the efficiency of irreversible heat engine.
Here, W is the work done, QH is the heat transfer in and QL is the heat transfer out.
Calculation:
We know that,
Two engines have same QH, thus
Conclusion:
The heat transfer out in reversible engine is less than the heat transfer out in irreversible engine.

The base is maintained at T. and the surface of the fin exchanges heat by convection to an ambient fluid at T with a heat transfer coefficient h. It is desired to increase the heat transfer from the fin. The following suggestions are made: (i) doubling k, (ii) doubling ro, (iii) doubling h. Which suggestion will bring about the largest increase in heat transfer? To x h, T C A h, Tarrow_forward
- A 20 cm long 304 stainless steel bar is initially at 18°C. One end of the bar is suddenly maintained at 100°C. Assuming that your finger can tolerate a 60°C temperature, what is the longest time you are willing to wait before you touch the other end?
