A vertical plate 2.5 m high, maintained at a uniform temperature of 54°C, is exposed to saturated steam at atmospheric pressure.
(a) Estimate the condensation and heat transfer rates per unit width of the plate.
(b) If the plate height were halved, would the flow regime stay the same or change?
(c) For 54 ≤ Ts ≤ 90°C, plot the condensation rate as a function of plate temperature for the two plate heights of parts (a) and (b).
