On a hot humid summer day, the air can be considered saturated steam at 950C. If you were to take an ice-cold beverage (40C) from the cooler, you would notice drop-wise condensation on the side of the can forming. What is the condensation heat transfer coefficient for the cold can? Assume the can is 12-cm tall and has a diameter of 8-cm.
Air at 90°C and 1.00 atm (absolute) contains 10.0 mole% water. A continuous stream of this air enters a compressor-condenser, in which the temperature is lowered to 15.6°C and the pressure is raised to 3.00 atm. The air leaving the condenser is then heated isobarically to 100°C. Calculate: (a) the fraction of water that is condensed from the air (b) the relative humidity of the air at 100°C (c) and the ratio of the volumetric flow of the outlet air to the volumetric flow of the feed air.
