Problem 87P

Humid air is to be conditioned in a constant pressure process at 1 atm from 39°C dry bulb and 50 percent relative humidity to 17°C dry bulb and 10.8°C wet bulb. The air is first passed over cooling coils to remove all of the moisture necessary to achieve the final moisture content and then is passed over heating coils to achieve the final state.

(a) Sketch the psychometric diagram for the process.

(b) Determine the dew point temperature of the mixture at the inlet of the cooling coils and at the inlet of the heating coils.

(c) What is the net heat transfer for the entire process for this process, in kJ/kg dry air?

RESPIRATORY PHYSIOLOGY  Example exam question: You’re driving your horse to a race, and there is a hole in the trailer near the exhaust pipe. By the time you get to the horse race, you open the door and what happens (There will be a wreck and the horse will bleed out, this will involve the cardiovascular system) o The horse falls out dead.  The major function of the respiratory system is the exchange of gases. o Two major gases we exchange are carbon dioxide and oxygen. o We are dependent upon the concentration of the gases in the air we breathe (the atmosphere.) If the concentration changes, that disrupts the respiratory system.  Going up really high, there’s not much oxygen. We ar
