Question

Mark the wrong statement with respect to laminar flow condensation on a vertical plate

Options:

A . The rate of condensation heat transfer is maximum at the upper edge of the plate and progressively decreases as the lower edge is approached

B . The average heat transfer coefficient is two third of the local heat transfer coefficient at the lower edge of the plate

C . At a definite point on the heat transfer, the film coefficient is directly proportional to thermal conductivity and inversely proportional to thickness of film at the point

D . The film thickness increases as the fourth root of the distance down the upper edge

Answer: Option B
Answer: (b).The average heat transfer coefficient is two third of the local heat transfer coefficient at the lower edge of the plate
