Unformatted text preview: a.) You want to design the heater so that it completely eliminates any heat loss from the skin. What is the heat transfer per unit area required? b.) In order, rate the importance of the following design parameters to your result from (a): k ins , k ext , and . c.) Plot the heat transfer per unit area required to eliminate heat loss as a function of the emissivity, . While the average emissivity of the suit's external surface is = 0.25, you have found that this value can change substantially based on how dirty or polished the suit is. You are worried about these local variations causing the astronaut discomfort due to local hot and cold spots. d.) Assume that the heater power is kept at the value calculated in (a). Plot the rate of heat transfer from the skin as a function of the fractional change in the emissivity of the suit surface....
