Example 2.2n. Air at 30°C and 150 kPa in a closed container is compressed and cooled. It is found that the first droplet of water condenses at 200 kPa at 15°C. Calculate the percent relative humidity of the original air. The vapour pressures of water at 15° and 30°C are 1.7051 kPa, and 4.246 kPa, respectively.
