The heat transfer co-efficient in film type condensation is __________ that for dropwise condensation.

ANS:B - lower than

In film type condensation, the heat transfer coefficient is typically lower than that for dropwise condensation. Dropwise condensation occurs when individual droplets form on the condensing surface, leading to reduced contact area between the condensing vapor and the surface. This reduced contact area results in higher heat transfer coefficients compared to film condensation, where a continuous film of condensate covers the surface. In film condensation, the layer of condensate acts as an insulating barrier, reducing the rate of heat transfer. Therefore, the correct answer is: lower than.
