Homework Help: Thermodynamics/Entropy Question

  1. Dec 5, 2007 #1
    1. The problem statement, all variables and given/known data
    An 82-kg parachutist descends through a vertical height of 350 m with constant speed. Find the increase in entropy produced by the parachutist, assuming air temperature of 21 degrees C.

    2. Relevant Equation
    S = Q/T


    3. The attempt at a solution
    I believe I can find work via W = mgh or (82)(9.81)(350) = 281,547 J. What can I do from there.

    Thanks in advance.

    Can I assume the body temperature is 37 degrees C? Do I need to? I cannot figure out how to find hot temperature and heat transfered. Are there any ideas on how I can convert W in this situation into something useful to further the problem? Any hints towards the right direction would be appreciated.
