Outer surface of a tube-steel oven is at 110 oC. What would be the heat transfer rate to
the surrounding air at 25 oC. if the natural convective heat transfer coefficient is
h = C (Ts – Ta)1/4
where; C= 4.5 W/(m2.K5/4), Ta and Ts are air temperature and surface temperature,
respectively. Surface area of the wall is 125 m2.
