True/False question: (Answer format: True True True True False) 6. When hot and cold fluids exchange heat, the temperature difference for heat transfer is greater when they flow in parallel than when they flow counterflow. 7.

During the condensation operation of the heat exchanger, non-condensable gases on the steam side should be discharged regularly. 9. The heat load refers to the heat exchange capacity inherent in the heat exchanger itself. 10. The most effective way to increase the heat transfer rate is to increase the heat transfer area.
