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?
