Participation reward: 2 Wealth. Reward for correct answer: 9 wealth. In a heat exchanger, if the fluid on one side is undergoing a condensation process (phase change) while the fluid on the other side is a single-phase fluid that is heated from a low temperature to a high temperature, which of the following statements is correct? A. Counterflow can achieve a larger heat transfer temperature difference than coflow. B. Coflow can achieve a larger heat transfer temperature difference than counterflow. C. Both counterflow and coflow can yield the same temperature difference. D. Vertical cross-flow can achieve the maximum heat transfer temperature difference. [Haichuan Thanksgiving] -- Production Area.
