Question wording?

[djshortsleeve]

One problem I did last night, a ventilation problem, had some pretty tricky wording. It was stated that "conditioned air enters the room and increases 20 deg F." From this, we are to infer that the temperature of the air entering the room is the indoor setpoint, minus 20 deg.

Is there alot of this tricky wording on the exam?

Ok, that kind of thing is important. Yes you will find some of these in the exam (Im going for third rodeo next week). Keep your eyes open and whenever possible try to use enthalpies for better accuracy (Q= Mdot X dh). Wish you success too...
