Mark the wrong statement with respect to laminar flow condensation on ...
Wrong Statement: The average heat transfer coefficient is two thirds of the local heat transfer coefficient at the lower edge of the plate (Option B).
Explanation:
Laminar flow condensation occurs when a vapor condenses onto a cooler surface. In this case, the vertical plate acts as the cooler surface onto which the vapor condenses. The condensation process involves heat transfer from the vapor to the plate.
Statement Analysis:
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.
This statement is correct. In laminar flow condensation, the rate of heat transfer is highest at the upper edge of the plate because the vapor condenses more rapidly in that region. As we move towards the lower edge of the plate, the condensation rate decreases.
c) At a definite point on the heat transfer, the film coefficient is directly proportional to thermal conductivity and inversely proportional to the thickness of the film at the point.
This statement is correct. The film coefficient represents the ability of the condensing film to conduct heat. It is directly proportional to the thermal conductivity of the film, which measures how well heat can be conducted through the film. The film coefficient is inversely proportional to the thickness of the film at a specific point, as a thicker film hinders heat transfer.
d) The film thickness increases as the fourth root of the distance down the upper edge.
This statement is correct. In laminar flow condensation, the film thickness increases as we move down the upper edge of the plate. The relationship between film thickness and distance down the plate is given by the fourth root relationship. This means that the film thickness increases less rapidly as we move down the plate.
Correct Statement:
b) The average heat transfer coefficient is two thirds of the local heat transfer coefficient at the lower edge of the plate.
This statement is incorrect. The average heat transfer coefficient is not two thirds of the local heat transfer coefficient at the lower edge of the plate. The average heat transfer coefficient represents the overall heat transfer rate over the entire plate, while the local heat transfer coefficient represents the heat transfer rate at a specific point on the plate. The average heat transfer coefficient is typically lower than the local heat transfer coefficient because it takes into account the variations in heat transfer along the plate. Therefore, option B is the wrong statement.
