As part of a heat treatment process, cylindrical, 304 stainless steel rods of 125-mm diameter are cooled from an initial temperature of 500C by suspending them in an oil bath at 30C. If a convection coefficient of 400 W/m^2K is maintained by circulation of the oil, how long does it take for the centerline of a rod to reach a temperature of 50C, at which point it is withdrawn from the bath? If 10 rods of length L =1m are processed per hour, what is the nominal rate at which energy must be extracted from the bath (the cooling load)?
