Answer:
Explanation:
Given that:
diameter = 100 mm
initial temperature = 500 ° C
Conventional coefficient = 500 W/m^2 K
length = 1 m
We obtain the following data from the tables A-1;
For the stainless steel of the rod
Here, we can't apply the lumped capacitance method, since Bi > 0.1
However, on a single rod, the energy extracted is:
Hence, for centerline temperature at 50 °C;
The surface temperature is:
