Question:

Calculate the rate of heat loss from a human body at 37?C in an air stream of 5 m/s, 35?C. The body can be modeled as a cylinder 30 cm in diameter, 1.8 m high. Compare your results with those for natural convection from a body and with the typical energy intake from food, 1033 kcal/day (Problem 5.8).GIVENHuman body modeled as a cylinder in an air streamBody surface temperature (Ts) = 37?CAir velocity (V??) = 5 m/sAir temperature (T??) = 35?CCylinder diameter (D) = 30 cm = 0.3 mCylinder height (H) = 1.8 mASSUMPTIONSAir velocity is perpendicular to the axis of the cylinderAir flow approaching cylinder is laminarHeat transfer from the ends can beneglected
