Q. Pick out the wrong statement. (Solved)
1. The condensing film co-efficient is about 3 times lower for vertical condenser as compared to the equivalent horizontal condenser for identical situation
2. Film co-efficient for vaporisation decreases as a result of vapor binding
3. In industrial practice, sub-cooling of condensate is required, when the condensate is a volatile liquid and is to be transferred for storage
4. Overall heat transfer co-efficient in a heat exchanger is controlled by the value of the film coefficient, which is higher
- d. Overall heat transfer co-efficient in a heat exchanger is controlled by the value of the film coefficient, which is higher
