5- 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 ºC. The tank is covered with a 4-cm-thick layer of an insulation (k=0.25 W/m.K). The surrounding air is at 15ºC. The inside and outside heat transfer coefficients are 35 and 10W/m2.K, respectively.

Required: Draw the thermal resistance network (thermal circuit) and label the associated
resistance and determine the following:
a) The individual thermal resistance associated with the thermal circuit.
b) The total thermal resistance value
c) The rate of heat transfer
d) The temperature difference across the tank shell and the insulation layer.
