A vertical rectangular water duct 1 m high and 0.1 m deep is placed in an environment of saturated steam at atmospheric pressure. If the outer surface of the duct is about 50?C, estimate the rate of steam condensation per unit length.GIVENWater-cooled rectangular duct, 1 m high, 0.1 m deepDuct surface is 50?CSteam environmentASSUMPTIONSThe steam is at 1 atmosphere pressureCondensation from the horizontal duct surfaces can be neglectedLaminar film condensation on the vertical surfaces (must bechecked)
