Heat Transfer A steel sphere of radius 0.1 m at 400°K is immersed in an oil at 300°K. If the centre of the sphere reaches 350°K in 20 minutes, how long will it take for a 0.05 m radius steel sphere to reach the same temperature (at the centre) under identical conditions ? Assume that the conductive heat transfer co-efficient is infinitely large. 20 minutes 40 minutes 10 minutes 5 minutes 20 minutes 40 minutes 10 minutes 5 minutes ANSWER DOWNLOAD EXAMIANS APP
