Chapter 10.3, Problem 89ES

(a)

To determine

To calculate: The estimate of the wind chill temperature (to the nearest tenth of a degree) for the actual temperature $T=7°C$ and wind speed $v=8\text{ m/sec}$ when the temperature is $T$ degree Celsius and the wind speed is $v$ meters per second, the wind chill temperature, $T_w$, is the temperature (with no wind) that it feels like. The formula for finding the wind chill temperature is $T_w=33-\frac{\left(10.45+10\sqrt{v}-v\right)\left(33-T\right)}{22}$.

(b)

To determine

To calculate: The estimate of the wind chill temperature (to the nearest tenth of a degree) for the actual temperature $T=0°C$ and wind speed $v=12\text{ m/sec}$ when the temperature is $T$ degree Celsius and the wind speed is $v$ meters per second, the wind chill temperature, $T_w$, is the temperature (with no wind) that it feels like. The formula for finding the wind chill temperature is $T_w=33-\frac{\left(10.45+10\sqrt{v}-v\right)\left(33-T\right)}{22}$.

(c)

To determine

To calculate: The estimate of the wind chill temperature (to the nearest tenth of a degree) for the actual temperature $T=-5°C$ and wind speed $v=14\text{ m/sec}$ when the temperature is $T$ degree Celsius and the wind speed is $v$ meters per second, the wind chill temperature, $T_w$, is the temperature (with no wind) that it feels like. The formula for finding the wind chill temperature is $T_w=33-\frac{\left(10.45+10\sqrt{v}-v\right)\left(33-T\right)}{22}$.

(d)

To determine

To calculate: The estimate of the wind chill temperature (to the nearest tenth of a degree) for the actual temperature $T=-23°C$ and wind speed $v=15\text{ m/sec}$ when the temperature is $T$ degree Celsius and the wind speed is $v$ meters per second, the wind chill temperature, $T_w$, is the temperature (with no wind) that it feels like. The formula for finding the wind chill temperature is $T_w=33-\frac{\left(10.45+10\sqrt{v}-v\right)\left(33-T\right)}{22}$.
