In a device to produce potable water, humid air at 90°F, 29.7 in Hg and 95% relative humidity is cooled to 40°F at constant pressure. If 10.0 gal/min of condensed water out of the device is desired calculate the following:
a) The mole fraction of water in the feed stream (in tophat include four digits past decimal)?
b) The mole fraction of water in the exit stream (in tophat include four digits past decimal)?
c) The volumetric flow rate of air into the cooler (ft3/min) (in tophat to nearest whole number)?
d) What is the dew point temperature of the inlet stream (in tophat to the nearest tenth)?
e) How many degrees of superheat (in °F ) does the inlet stream have (in tophat to the nearest tenth)?
At 50 °C, 1.2 bar, the system n-pentane (1), n-hexane (2), and n-heptane (3) exists ion vapor-liquid equilibrium. The mole fractions in the two phases are: x1 = 0.6, x2 = 0.2, x3 = 0.2 in the liquid; and y1 = 0.87, y2 = 0.1, y3 = 0.03 ..
