Air enters a finned coil at 80 F db, 67 F wh, and standard atmospheric pressure. The chilled water has a temperature of 50 F at this position in the coil. Will moisture condense from the air for the following assumed conditions? Copper tubes with wall thickness of 0.018 in. and ther-

mal conductivity of 190 Btu/(ft-hr-F). The heat-transfer coefficient on the inside of the tubes is 1000 Btu/(hr-ft2-F). The product of total heat-transfer coefficient and surface effectiveness
