Pick out the wrong unit conversion of mass transfer co-efficient?
Correct answer: D. 1 kg/hr.m2 = 4.8823 lb/hr.ft2
- A. 1 lb/hr.ft3.atm. = 4.8182 kg/hr.m2.bar
- B. 1 kg/hr.m2.atm= 0.98687 kg/hr. m .bar
- C. 1 lb/hr.ft2 = 4.8823 kg/hr.m2
- D. 1 kg/hr.m2 = 4.8823 lb/hr.ft2
Explanation
Since 1 kg equals about 2.2046 lb and 1 m2 equals 10.764 ft2, 1 kg/(h·m2) equals about 0.2048 lb/(h·ft2), not 4.8823. The factor 4.8823 applies in the reverse conversion, so d is the wrong conversion.
