As part of a heat treatment process, cylindrical, 304 stainless steel rods of 100-mm diameter are cooled from an initial temperature of 500ºC by suspending them in an oil bath at 25ºC. If a convection coefficient of 500 W/m²·K is maintained by circulation of the oil, how long does it take for the centerline of a rod to reach a temperature of 52ºC, at which point it is withdrawn from the bath? If 9 rods of length 1 m are processed per hour, what is the nominal rate at which energy must be extracted from the bath (the cooling load)?

In a manufacturing process, stainless steel cylinders (AISI 304) initially at 600K are quenched by submersion in an oil bath maintained at 300K with h=500W/m2-K. Each cylinder is of length 2L=60 mm and diameter D=80mm. Consider a time 3 min into the cooling process and determine the temperatures at the center of the cylinder, at the center of the circular face and at the mid height of the site. (Use the Heisler charts to answer these questions). You may evaluate...
