The wall of a refrigerator is constructed of fiberglass insulation (k = 0.035 w/m·k) sandwiched between two layers of 0.161-m-thick sheet metal (k = 15.1 w/m·k). the refrigerated space is maintained at 3°c, and the average heat transfer coefficients at the inner and outer surfaces of the wall are 4 w/m2·k and 9 w/m2·k, respectively. the kitchen temperature averages 25°c. it is observed that condensation occurs on the outer surfaces of the refrigerator when the temperature of the outer surface drops to 20°c. determine the minimum thickness of fiberglass insulation that needs to be used in the wall in order to avoid condensation on the outer surfaces

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
