Q. Pick out the wrong statement. (Solved)
1. Superheated steam is preferably not used for process heating because of its low heat transfer film co-efficient
2. In a shell and tube heat exchanger, the shell pressure drop is maximum for orifice baffles
3. S.I. unit of fouling factor is Watt/m2 .°K
4. Longitudinal fins are used in extended surface heat exchangers, when the direction of fluid flow is parallel to the axis of the tube
- c. S.I. unit of fouling factor is Watt/m2 .°K
