On a hot summer day at Tallahassee, FL, the temperature of the outside air is 35°C and the pressure is 103kPa. The relative humidity is 90%. An air conditioner draws in outside air, cools it to 20°C, and delivers it at a rate of 528.5 mol/h. a. Draw and label a flow chart. How many independent mass balances can be written for this system? Write the maximum number of independent mass balances. b. Calculate the rate of moisture condensation (mol/h) and the volumetric flow rate of the air drawn from the outside (hint, you can assume air obeys the ideal gas law).

Question
Transcribed Image Text:1. On a hot summer day at Tallahassee, FL, the temperature of the outside air is 35°C and the
pressure is 103kPa. The relative humidity is 90%. An air conditioner draws in outside air,
cools it to 20°C, and delivers it at a rate of 528.5 mol/h.
a.
Draw and label a flow chart. How many independent mass balances can be
written for this system? Write the maximum number of independent mass
balances.
b. Calculate the rate of moisture condensation (mol/h) and the volumetric flow rate
of the air drawn from the outside (hint, you can assume air obeys the ideal gas
law).
