Problem: Cypher metrics problem 15, a thousand CFM of air 76 degrees and 60% relative humidity is removed from a room.
Given: 300 CFM is cooled to 54 degrees dry bulb and 52 degrees wet bulb; 700 CFM is being bypassed because 300 is being cool...
Approach: 300 CFM is cooled to 54 degrees dry bulb and 52 degrees wet bulb.
Calc: We know that it's 76 degrees dry bulb and 60% relative humidity in the room.
Calc: But 700 CFM is being bypassed because 300 is being cooled by a coil and the remaining bypasses.
Result: And that results in a mixed humidity ratio of 0.0104 pounds of water per pound of drier.
