Pick out the wrong statement.
A)The controlling resistance in case of heating of air by condensing steam is in the air film
B)The log mean temperature difference (LMTD) for counter flow and parallel flow can be theoretically same when any one of the fluids (hot or cold fluid) passes through the heat exchanger at constant temperature
C)In case of a 1 - 2 shell and tube heat exchanger, the LMTD correction factor value increases sharply, when a temperature cross occurs
D)Phase change in case of a pure fluid at a given pressure from liquid to vapor or vice-versa occurs at saturation temperature

Question

Quizplus · Accepted Answer

The LMTD correction factor does not increase sharply when a temperature cross occurs; instead, it is used to correct the LMTD in situations where the simple LMTD approach does not apply accurately, such as in complex flow arrangements or when there is a temperature cross. The statement suggests an incorrect relationship between the correction factor and temperature cross conditions.
