A billet of steel 30.5 cm in diameter, 61 cm long, initially at 645 K, is immersed in an oil bath that is maintained at 310 K. If the surface conductance is 34 W/m^2-K, determine the center temperature of the billet after 1 hour.

Step 1
This method simplifies the problem by assuming that the temperature difference within the object (the steel billet in this case) is negligible compared to the temperature difference between the object and its surroundings. This approach is valid under certain Show more…

A steel cylinder, 10 cm in diameter, is initially at T = 300°C. It is suddenly immersed in an oil bath that is maintained at T = 40°C, with h = 280 W/m^2K. a) Find the temperature at the center axis of the cylinder at t = 10 min. b) Find the surface temperature of the cylinder at that time. p = 7820 kg/m^3, C = 460 J/kgK, a = 0.44x10^-5 m^2/s.

A long, 0.6 m OD 347 stainless steel (k = 14 W/m K) cylindrical billet at 16°C room temperature is placed in an oven where the temperature is 260°C. If the average heat transfer coefficient is 170 W/m² K, (a) estimate the time required for the center temperature to increase to 232°C, and (b) determine the instantaneous surface heat flux when the center temperature is 232°C. (c) repeat part (a) but for a case where the billet is 1.2 m in length and the same heat transfer coefficient can be applied to all the surfaces.

A stainless-steel sphere [k = 16 W/m·°C] having a diameter of 4 cm is exposed to a convection environment at 20°C, h = 15 W/m^2·°C. Heat is generated uniformly in the sphere at the rate of 1.0 MW/m^3. Calculate the steady-state temperature for the center of the sphere.
