Question

CHO Fundamentals (5pts) Sphere: V-4/3. As-4tr, cylinder Acar. As-DLV-ALO-567x10-re ) A 1-m-inner-diameter liquid-oxygen spherical storage tank at a hospital keeps the liquid oxygen at T- -183.15°C·The tank wall is 0.1m-thick (K=0.02 W/m-K). The tank exterior is exposed to the surrounding which temperature is at 20°C and the radiation heat transfer coefficient on the exterior side of the tank wall is hr-5 W/m2-K 2-(1) If the contact resistance is neglected between oxygen liquid and the interior tank wall, the temperature of interior tank wall (°C) is most nearly (A)-183.15 (B) -130.15 (C)-90.15 (D) 20 2-(2) The temperature of the exterior surface of the tank wall (°C) is most nearly (A)-13 (B)-3 (C)2 (D) 9 (E) 13
