A swamp cooler or misting fan is a fan that blows air in addition to a fine mist of water. Swamp coolers are often used by restaurants and bars in dry, hot climates to cool their outdoor seating areas. You want to make your own swamp cooler by attaching a water line to your fan that has an inlet capacity is 50.0 ft/min of air. The meteorologist says that today's high temperature will be 89 F and the relative humidity will be 20%. In order for you to enjoy your outdoor patio experience, the air coming out of the fan must be 78 For cooler. Approximate the swamp cooler's operation as an adiabatic spray cooler in order to estimate the relative humidity of the fan's output and the minimum flow rate of water entering the fan required to operate the swamp cooler under the given conditions. To solve for the requested values, first label the process flow diagram. Label any quantities as "unknown" if they are not given or implied in the question. Do not leave any blank spaces. Variable names are given for reference Inter. Answer Bank V = air/min unknown 78 20 89 500 M Ib dry air/min T.

V fair/min Ib dry air/min 7 F relative humidity What is the relative humidity of the adiabatically cooled air at 78 F? relative humidity: What is the humid volume of gas at 89 F and 20% relative humidity? humid volume: ib dry it What is the mass flow rate of dry air into the fan's inlet? Ib dry air/min mass flow rate: What is the absolute humidity of the fan's inlet air? What is the absolute humidity of the fan's inlet air? absolute humidity: ,0 ib dry air What is the absolute humidity of the cooled air? absolute humidity: ib dry air What is the minimum mass flow rate of water into the swamp cooler? 16 H,O/min minimum mass flow rate
