Question:

A stainless steel cylinder (18% Cr, 8% Ni) is heated to a uniform temperature of 200ºC and then allowed to cool in an environment where the air temperature is maintained constant at 30ºC. The convection heat-transfer coefficient may be taken as 200 W/m2 · ºC. The cylinder has a diameter of 10 cm and a length of 15 cm. Calculate the temperature of the geometric center of the cylinder after a time of 10 min. Also calculate the heat loss.
