In counter-flow heat exchangers, the fluids enter the exchanger from opposite ends. The current counter design is the most efficient. It can transfer the most heat from the heat (transfer) medium per unit mass because the average temperature difference along any unit length is higher.

Counter-flow heat exchangers are devices that transfer heat from one fluid to another fluid by bringing them into close contact without mixing them. In this process, the direction of the fluids is opposite to each other, meaning that one fluid flows in the opposite direction to the other fluid. The correct answer for the question is option 'B', which states that both the fluids at the inlet are in their hottest state.
Explanation:
- What is a counter-flow heat exchanger?
A counter-flow heat exchanger is a device that transfers heat between two fluids that are flowing in opposite directions. These fluids can be gases, liquids, or a combination of both.
- How does a counter-flow heat exchanger work?
The fluids flow in separate channels that are separated by a wall. When the fluids come in contact with the wall, heat is transferred from the hotter fluid to the cooler fluid. The heat transfer occurs due to the temperature difference between the two fluids.
- What is the direction of the fluids in a counter-flow heat exchanger?
In a counter-flow heat exchanger, the direction of the fluids is opposite to each other. This means that one fluid flows in the opposite direction to the other fluid.
- Why is option 'B' the correct answer?
Option 'B' is the correct answer because in a counter-flow heat exchanger, the hottest fluid is introduced at the inlet and flows in the opposite direction to the cooler fluid. As the fluids flow through the channels, heat is transferred from the hotter fluid to the cooler fluid. Therefore, both the fluids at the inlet are in their hottest state.
Conclusion:
In a counter-flow heat exchanger, the fluids flow in opposite directions. The hottest fluid is introduced at the inlet and flows in the opposite direction to the cooler fluid. Therefore, both the fluids at the inlet are in their hottest state.
