An engineer is investigating objects that can be used as a solar collector. One ofthe objects considered is the object made of aluminum and is coated with leadsulfate. Investigation shows that the reflectivity of this object is 0.2 for radiationat wavelengths less than 3.3 μm and 0.95 for radiation greater than 3.3 μm. Inorder to get better insight into the behavior of the object, as a candidate for asolar absorber, the object is then exposed to two different conditions: a solarradiation (T ~ 5800 K) and a room temperature (T ~ 300 K). What is the energyreflected by the object at these two conditions?

A long, horizontal, cylindrical steel reactor, 1 m in diameter, has a surface temperature of 300ºC. The emissivity of the steel is 0.6, and the heat transfer coefficient for natural convection is 5 W m−2 K−1 . Heat is lost by convection to the air at 15ºC, and also by radiation to the surroundings, which can be considered to be a black body at 15ºC. a) Calculate the total heat loss per metre length of the reactor, and the proportions lost by convection and radiation b) The reactor is then insulated with a thin layer of insulation material to reduce the total heat loss to one-tenth of its original value. This causes the surface temperature of the steel to rise to 400ºC. The thermal conductivity of the insulation is 0.01 W m−1 K−1 , and its surface emissivity is 0.2. Show that the resulting surface temperature of the insulation is about 89ºC, and calculate the thickness of insulation required, stating any assumptions made. Specifically need help with part b
