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 properties at the mean temperature of Tm=450K.
