Suppose the ambient conditions are: Temperature 25 C, relative humidity 40 %. You want to make a machine to obtain water from the air as shown below. In order to work you need a system to allow air to pass through the machine so that the water in it can be condensed. If you want to get one litter of water in a day (a) How many kilograms of air have to pass through the machine in a day? (b) If the radius of the duct is 0.1 m What would be the velocity of the air inside the duct? Machine to extract water from the ambient air R= 0.1 m Humid Air = 100 % T,= 10 C Liquid Water (1 t per day)
