The answer to question #4 is: 21%
This is calculated by determining the dew point for 61 degrees F at a relative humidity of 44%. From 61 degrees F move right until 44% is found. The dew point temperature of 39 degrees F is found directly above the 44% relative humidity. Then at a temperature of 83 degrees F, move to the right until the morning dew point temperature of 39 degrees F in reached. The relative humidity of 21% is directly below the 39 degrees F dew point.
