A cylindrical bottle with a diameter of 10 cm and a height of 30 cm contains cold water at 3 °C. The bottle is placed in windy air at 27°C. The temperature of the water is measured at 11 °C after 45 minutes of contact with the air. Neglecting radiation effects and heat transfer from the upper and lower surfaces, estimate the average wind speed.

In cold climates, weather reports usually give both the actual air temperature and the "wind-chill" temperature, which can be interpreted as follows. At the prevailing wind speed there is a rate of heat loss per unit area q, from a clothed person for an air temperature Te. The wind-chill temperature Twe is the air temperature that will give the same rate of heat loss on a calm day. Estimate the wind-chill temperature on a day when the air temperature is -10°C and the wind speed is 10m/s, giving a convective heat transfer coefficient of 50 W/m² K. A radiation heat transfer coefficient of 5 W/m² K can be used, and under calm conditions the convective heat transfer coefficient can be taken to be 5.0 W/m² K. Assume a 3 mm layer of skin (k = 0.35 W/m K), clothing equivalent to 8 mm-thick wool (k = 0.05 W/m K), and a temperature of 35°C below the skin. Also calculate the skin outer temperature.

During a performance test of an insulation wall, a 2 m long×3-m wide portion of the wall is placed in a wind tunnel. The wall is made of 1.2 cm thick siding, 20 cm thick brick, and 1 cm thick plaster layers. The test holds one side of the wall surface (the plaster surface) constant at 20°C as shown in the figure. During the test, air is flown parallel to the 2-m side of the wall over the other side (i.e., over the siding) of the wall. The air temperature is -15°C. The free-stream velocity of air is 5 m/s. Assume a film temperature of -10°C for air. Find out the rate of heat loss through the wall (i.e., from the rightmost surface in the figure to air on the left) during the test. Justify if the assumed value of film temperature is reasonable. The thermal conductivity of the siding, brick, and plaster are, respectively, 0.09 W/m-K, 0.7 W/m-K, and 0.82 W/m.K.
