174. For heat transfer purposes, a standing man can be modeled as a 30 cm diameter, 170 cm

long vertical cylinder with both the top and bottom surfaces insulated and with the side surface

at an average temperature of 34°C. For a convection heat transfer coefficient of 15 W/m2

-°C,

determine the rate of heat loss from this man by convection in an environment at 20°C.
