1. Saturated ethylene glycol vapor at 1 atm is exposed to a vertical plate 300 mm high and 100 mm wide hav- ing a uniform temperature of 420 K. Estimate the heat transfer rate to the plate and the condensation rate. Approximate the liquid properties as those corre- sponding to saturated conditions at 373 K (Table A.5).

2. 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).
