A 10-cm long, 10-cm diameter steel cylinder, whose thermal conductivity and thermal diffusivity are W 43 and 1.172 x 10 respectively, is taken out of a furnace with a uniform temperature of m-K 300°C. It is suddenly immersed in a cooling bath that is maintained at a constant temperature of 40°C and has a convection heat transfer coefficient of 280 m2-K Find the amount of heat loss from the cylinder after 2 minutes in kl. Express your answer as a positive value.
