Problem 1 (30): Dr. is working in the thermal laboratory where oil is stored at 150°C in a spherical container of 300 cm of internal diameter, the container was made with 3-cm-thick cooper (k - 386 W/m°C). The tank is covered with 8. cm-thick glass wool insulation (k - 0.05 W/m°C). Determine the heat loss to the surroundings at Toz-28 °C by natural convection and radiation, with a combined heat transfer coefficient of ha - 150 W/m2oC.
