A spherical tank with internal diameter of 2 m made of 2.0-cm-thick stainless steel (k=15 W/m.K) is used for storing a fluid at a temperature of 1 °C. The tank is covered with a 4-cm-thick layer of an insulation (k=0.25 W/m.K). The surrounding air is at 15 °C. The inside and outside heat transfer coefficients are 35 and 10 W/m2.K, respectively. Required: Draw the thermal resistance network (thermal circuit) and label the associated resistance and determine the following: а) b) c) The individual thermal resistance associated with the thermal circuit. The total thermal resistance value The rate of heat transfer
