Answer:
230.4W
Explanation:
Heat transfer by conduction consists of the transport of energy in the form of heat through solids, in this case a jacket.
the equation is as follows
![Q=\frac{KA(T2-T1)}{L} \\](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7BKA%28T2-T1%29%7D%7BL%7D%20%5C%5C)
Where
Q=heat
k=conductivity=0.04
A=Area=1.8m^2
T2=33C
T1=1C
L=thickness=1cm=0.01m![Q=\frac{(0.04)(1.8m^2)(33-1)}{0.01m}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%280.04%29%281.8m%5E2%29%2833-1%29%7D%7B0.01m%7D)
Q=230.4W
the skier loses heat at the rate of 230.4W
Answer:
A) Wet bulb temperature of #1 is less than that of #2
Explanation:
This can be gotten from pinpointing the states of the two containers on a psychometric chart.
