Transcribed Image Text:
A stream of air at 450.0 °C and 835 torr with a dew point of 30.0 °C flowing at a rate of 1915 L/s is to be cooled in a spray cooler.
A fine mist of liquid water at 15.0 °C is sprayed into the hot air at a rate of 110.0 g/s and evaporates completely.
The cooled air emerges at 1 atm.

Material Balances
For the flow diagram below, use two material balances and three constraints to determine all unknowns except for the outlet temperature T3.
A g H2O(l)/s
n2 (mol H2O(l)/s)
B °C
CL air/s
n₁ (mol/s)
x₁ (mol H2O (v) /mol)
(1-x) (mol DA/mol)
D °C, E torr
Tdp=F °C
n3 (mol/s)
X3 (mol H2O(v)/mol)
(1-x3) (mol DA/mol)
T3 (°C), 1 atm
Assume A = 110.0 g, B = 15.0 °C, C = 1915 L, D = 450.0 °C, E = 835 torr, F = 30.0 °C.
