Question

Suppose a hiker of weight W climbs a mountain of height H with an efficiency n on a cool day with temperature TA:

a) How many food calories are required?

b) How much thermal energy must the hiker shed (evaporation and radiation)?

c) How much thermal energy will the hiker radiate assuming an emissivity e if the hike takes blank time delta t?

d) How much water must the hiker perspire to shed the remainder of the thermal energy that was not radiated?

Choose your own (reasonable) values of W,H,theta,V,n, TA and e

Do one for a cool day and one for a hot day.

a) Food calories reqd. = (W*H/4.2)............................. b) (W*H/4.2) (1-n)........
