Fouling factor_____________________?
Correct answer: C. Accounts for additional resistances to heat flow
- A. Is a dimensionless quantity
- B. Does not provide a safety factor for design
- C. Accounts for additional resistances to heat flow
- D. None of these
Explanation
A fouling factor represents the added thermal resistance caused by deposits such as scale, corrosion products, or biological films. It is included in the overall resistance used to design for the reduced heat-transfer performance.
