Abstract
This article provides the analytical solution for an optimum fin shape of minimum volume under dehumidifying conditions, where the “length-of-arc assumption is eliminated and a linear relationship between humidity ratio and temperature of the saturated air is considered. The volume of the optimum circular wet fin obtained here is 9.49 times smaller than the volume of Hanin and Campo's (2003) dry fin and 58.91 to 75.89 times smaller than Schmidt's (1926) parabolic dry fin. The optimum wet circular fin is shorter in length and has a smaller base height than Hanin and Campo's fin. An effort is also made to analyze Schmidt's parabolic fin under dehumidification.
