Question

A skier wears a jacket filled with goose down that is 15 mm thick. Another skier wears a wool sweater that is 4.0 mm thick. Both have the same surface area. Assuming the temperature difference between the inner and outer surfaces of each garment is the same, calculate the ratio (wool/goose down) of the heat lost due to conduction during the same time interval.

          A skier wears a jacket filled with goose down that is 15 mm
thick. Another skier wears a wool sweater that is 4.0 mm thick.
Both have the same surface area. Assuming the temperature
difference between the inner and outer surfaces of each garment is
the same, calculate the ratio (wool/goose down) of the heat lost
due to conduction during the same time interval.

Step 1

Given: Thickness of wool sweater (t1) = 4.0 mm Thickness of goose down jacket (t2) = 15 mm Ratio (wool/goose down) = t1 / t2 Ratio (wool/goose down) = 4.0 mm / 15 mm Ratio (wool/goose down) = 4/15 Show more…
