【Daily Question】Chemical Engineering Principles 209: Heat Exchangers (October 21)
Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope for your active support! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying, and this thread will be closed after 1 day ! Participation earns 3 wealth points, with an additional 3 wealth points for correct answers~~~ True or False: The average heat transfer temperature difference of a heat exchanger refers to the difference between the average temperatures at the inlet and outlet of the hot fluid, and those at the inlet and outlet of the cold fluid.

True or False: The average heat transfer temperature difference of a heat exchanger refers to the difference between the average temperature at the inlet and outlet of the hot fluid and the average temperature at the inlet and outlet of the cold fluid. (cuo)
That’s wrong. It should be the temperature difference between the inlet and outlet of the hot and cold fluids.
The average heat transfer temperature difference of a heat exchanger refers to the difference between the average temperature at the inlet and outlet of the hot fluid and the average temperature at the inlet and outlet of the cold fluid. (Correct)
The average heat transfer temperature difference of a heat exchanger refers to the difference between the average temperature at the inlet and outlet of the hot fluid and the average temperature at the inlet and outlet of the cold fluid. ( x)
The average heat transfer temperature difference of a heat exchanger refers to the difference between the average temperature at the inlet and outlet of the hot fluid and the average temperature at the inlet and outlet of the cold fluid. (Yes)
It’s related to the fluid flow rate at the management level, I guess
The average heat transfer temperature difference of a heat exchanger refers to the difference between the average temperature at the inlet and outlet of the hot fluid and the average temperature at the inlet and outlet of the cold fluid. (×)
True or False: The average heat transfer temperature difference of a heat exchanger refers to the difference between the average temperature at the inlet and outlet of the hot fluid and the average temperature at the inlet and outlet of the cold fluid. ( ) is incorrect
