Consider a hot dog to have the following dimensions and properties: diameter

20 mm, c_p

3.35 kJ/kgK,


880 kg/m³, and k

0.5 W/mK. For the hot dog initially at 5C, exposed to boiling water at 100C, with a surface coefficient of 90 W/m²
K, what will be the cooking time if the required condition is for the center temperature to reach 80C?
