2 inch outer diameter throughout a plastic sheet milla 60 m long section of a horizontal steam pipefrom one end to the other, on which it passes without comparisonis observed. Ambient air and surface temperaturesAt 20 ° C, several hours measurements are the average of the exposed surfaces of the steam pipe.shows that its temperature is 160 ° C. The outer surface of the pipe appears to be oxidized andemissivity can be taken as 0.6. According to this;a) Calculate the heat loss in the steam pipe.b) Some steam is produced in a gas oven operating at 60% efficiency. Factory 105,500kJ natural gas pays $ 1.10. If it is assumed that the factory operates all year (365 days), for this facilitycalculating the annual cost of heat losses in the steam pipe.

Hi there! Can you help em figure this problem. I keep gettign 707 watts and that is not correct. Seals may cool themselves by using thermal windows, patches on their bodies with much higher than average surface temperature. Suppose a seal has a 0.030 m2 thermal window at a temperature of 30∘C. If the seal's surroundings are a frosty -15 ∘C, what is the net rate of energy loss by radiation? Assume an emissivity equal to that of a human. Express the answer in watts. Thank you for the help! It is appreicated.
3) The temperature and emissivity of the glass of a flat plate collector with a dth of 1 m and a length of 1.8 m are 40°C and 0.9, respectively. The absorber plat painted with matte black paint and the temperature of the plate is 80°C. Th issivity and absorptivity of matte black paint are equal to each other and are 0. e absorber plate is then coated with selective material with emissivity an orptivity of 0.2 and 0.9, respectively. In this case, by what percentage does the ount of heat from the plate change?
