Question

Problem

1. If I have air at 100 kPa and (a) -10^oC, (b) 45^oC, and (c) 110^oC, what is the maximum absolute humidity I can have?

2. A new high-efficiency home heating system includes an air-to-air heat exchanger that uses energy from outgoing stale air to heat the fresh incoming air. If the outside ambient temperature is -10^oC and the relative humidity is 50%, how much water will have to be added to the incoming air if it flows in at the rate of 1 m³/s and must eventually be conditioned to 20^oC and 45% relative humidity?

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
