During a plant visit, it was noticed that a 12-m-longsection of a 10-cm-diameter steam pipe is completelyexposed to the ambient air. the temperature measurementsindicate that the average temperature of the outer surface ofthe steam pipe is 75°c when the ambient temperature is 5°c. there are also light winds in the area at 10 km/h. the emissivity of the outer surface of the pipe is 0.8, and the averagetemperature of the surfaces surrounding the pipe, includingthe sky, is estimated to be 0°c. determine the amount of heatlost from the steam during a 10-h-long work day
