A semi-nude jogger (with shorts and footwear) decides to exercise in a shaded area (Ta = Tg) of an indoor stadium based on his concept of being in shade will

protect him from heat disorders. If the air temperature (Ta) is 33.5°C (92°F) andthe relative humidity (RH) is 68%, assuming the jogger progresses at an average speed (V) of 4.5 mph (2 m/s) with calm wind conditions, do you find the jogger's decision to exercise at that particular time to be unwise? Defend your finding by detailed calculations. Given: Jogging at 4.5 mph, M =1800 Btu/hr or 450 kcal/hr.
