Homework Equations
Dew Point Temperature T = Saturated Temperated at Vapor Pressure
Partial Pressure = (mole fraction) x (Mixture Pressure)
The Attempt at a Solution
The dew point temperature is only dependent on the pressure of the water vapor in the mixture. This pressure is equal to
P (vapor) = 0.15 (100 kPa) = 15 kPa. Using the saturation tables, the temperature corresponding to this pressure is 53.97 degrees Celsius.
The 2nd part is where I am having difficulty. The temperature cools down to 43.97 degrees Celsius. Now I have to find the mass flow rate of the water to determine how much time it will take to collect 10kg of water. This means I need to determine the mass flow rate of the vapor too? I know the mole fractions add up to 100%
