Pick out the wrong unit conversion of heat transfer rate?
Correct answer: B. 1 Watt = 1.163 kcal/hr
- A. 1 kcal/hr= 1.163 Watt
- B. 1 Watt = 1.163 kcal/hr
- C. 1 BTU/ft2.hr = 2.712 kcal/m2.hr
- D. 1 kcal/m2.hr = 0.3687 BTU/ft2.hr = 1.163 Watt/m2
Explanation
One watt equals approximately 0.8598 kcal/hr, so 1 kcal/hr equals 1.163 W, not the reverse. The conversion in option B therefore has its direction and value reversed.
