What is the exit relative humidity and the heat transfer

Question

Problem

1. A saturated air-water vapor mixture at 20^oC, 100 kPa is contained in a 5-m- closed tank in equilibrium with 1 kg liquid water. The tank is heated to 80^oC. Is there any liquid water in the final state? Find the heat transfer for the process.

2. A flow of 0.2 kg/s liquid water at 80^oC is sprayed into a chamber together with 16 kg/s dry air at 60^oC. All the water evaporates, and the air leaves at 40^oC. What is the exit relative humidity and the heat transfer?

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.
