For an asbestos cylinder with both height and diameter of 13 cm initially at a uniform temperature of 295 K placed in a medium at 810 K with an associated convective heat-transfer coefficient of 22.8 W/m²
K, determine the time required for the center of the cylinder to reach 530 K if end effects are neglected.
