Heat Transfer

Q1:

Pick out the wrong statement.

A Superheated steam is preferably not used for process heating because of its low heat transfer film co-efficient.

B In a shell and tube heat exchanger, the shell pressure drop is maximum for orifice baffles.

C S.I. unit of fouling factor is Watt/m2.°K.

D Longitudinal fins are used in extended surface heat exchangers, when the direction of fluid flow is parallel to the axis of the tube.

ANS:C - S.I. unit of fouling factor is Watt/m2.°K.

The wrong statement is: c) S.I. unit of fouling factor is Watt/m².°K. The correct SI unit of fouling factor is °C.m²/W or m².°C/W, not Watt/m².°K. So, the correct answer is: c) S.I. unit of fouling factor is Watt/m².°K.
