A stream of air at 500.0 °C and 835 torr with a dew point of 10.0 °C flowing at a rate of 1515 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 120.0 g/s and evaporates completely.

The cooled air emerges at 1 atm.

For the flow diagram below, use two material balances and three constraints to determine all unknowns except for the outlet
temperature T3.
A g H20(1)/s
n2 (mol H,O(1)/s)
B °C
C L air/s

D °C, E torr
Tdo =
X3 (mol H20(v)/mol)
(1-x3) (mol DA/mol)
T3 (C), 1 atm
F °C
Assume A = 120.0 g, B = 15.0 °C, C = 1515 L, D = 500.0°C, E = 835 torr, F = 10.0°C.
