A standing human in a bathing suit with legs and arms to the side can be approximated as a cylinder of 0.3 m diameter and 1.75 m in length with a surface temperature of 30o C. Calculate the heat loss in a 10 m/s wind at 20o C before jumping in the pool. Compare this the heat loss from someone who just jumped out of a swimming pool and their skin is covered with a thin layer of water at 30o C and the relative humidity of the air is 60%. The wind is still 10 m/s and 20o C. If you are using the Zukauskas correlation the Pr/Prs part is negligible with mass transfer (e.g. Sc/Scs = 1). Also be aware of what temperature the properties should be evaluated.
