When one of the fluids is highly corrosive and has fouling tendency, it should_____________________?
Correct answer: C. Preferably flow inside the tube for its easier internal cleaning
- A. Flow at a very slow velocity
- B. Preferably flow outside the tube
- C. Preferably flow inside the tube for its easier internal cleaning
- D. Flow outside the tube, when the flow is counter-current and inside the tube when the flow is
- E. co-current
Explanation
A corrosive, fouling fluid is preferably passed through the tubes because the tube side can be mechanically or chemically cleaned more readily. Keeping it outside would make cleaning the shell side more difficult.
