Thread Content
This post was last edited by “Back to Cambridge” on December 26, 2015, at 09:30. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! Participation earns 3 wealth points, with an additional 3 wealth points awarded for correct answers~~ Multiple-choice question: Cooling water flows inside a single cooling coil in a reactor, with inlet and outlet temperatures of t1? and t2? respectively. A hot fluid flows steadily outside the coil, and a stirrer is used to maintain a uniform temperature T for this hot fluid (where T is the outlet temperature of the hot fluid). If the length of the cooling coil is doubled while all other conditions remain unchanged, what will happen to the outlet water temperature t2?. A. Increase B. Decrease C. Remain unchanged D. Not necessarily A
A. Increase. －－－－－－－－－－－－－－－－－－－－－－
Cooling water is circulated within a single cooling coil in the reactor, with inlet and outlet temperatures of t1? and t2?, respectively. A hot fluid flows steadily outside the coil; thanks to the action of the stirrer, this hot fluid maintains a uniform temperature T (where T is the temperature at the outlet of the hot fluid). If the length of the cooling coil is doubled while all other conditions remain unchanged, what will be the value of the outlet water temperature t2?. (A) A. Increase B. Decrease C. Remain unchanged D. Not necessarily

The correct answer to this question should be A.
Cooling water is passed through a single cooling coil inside the reactor, with inlet and outlet temperatures of t1? and t2?, respectively. A hot fluid flows steadily outside the coil; thanks to the action of a stirrer, this hot fluid maintains a uniform temperature T (where T is the temperature at the outlet of the hot fluid). If the length of the cooling coil is doubled while all other conditions remain unchanged, then the outlet water temperature t2? should (A increase).
