Using the information in Problem 1.22, estimate the ambient air temperature that could cause frostbite on a calm day on the ski slopes. 1.22 In order to prevent frostbite to skiers on chair lifts, the weather report at most ski areas gives both an air temperature and the wind-chill temperature. The air temperature is measured with a thermometer that is not affected by the wind. However, the rate of heat loss from the skier increases with wind velocity, and the wind-chill temperature is the temperature that would result in the same rate of heat loss in still air as occurs at the measured air temperature with the existing wind. Suppose that the inner temperature of a 3-mm-thick layer of skin with a thermal conductivity of 0.35W/mKis35C and the air temperature is 20C. Under calm ambient conditions the heat transfer coefficient at the outer skin surface is about 20W/m2K (see Table 1.4), but in a 40-mph wind it increases to 75W/m2K. If frostbite occurs when the skin temperature drops to about 10C, do you advise the skier to wear a face mask? What is the skin temperature drop due to the wind?

A particular processing facility heats and sterilises 500 kg of unprocessed honey every 30 minutes. The unpro- cessed honey is stored in large vats, then pumped though pipes into heating units before being pumped through another pipe to be bottled. The pipe carrying the honey from a storage container, which is 11 m tall, to a heating unit is 5 m long and has a diameter of 10 cm. Prior to being heated the honey is kept at 25°C.

2. An air parcel at 950 mb has a temperature of 14°C and a mixing ratio of 8 g/kg. What is the wet-bulb potential temperature of the air? The air parcel is lifted to the 700 mb level by passing over a mountain, and 70% of the water vapor that is condensed out by the ascent is removed by precipitation. Determine the temperature, potential temperature, mixing ratio, and wet-bulb potential temperature of the air after it has returned to the 950 mb level on the other side of the mountain.
