Question
Problem 1
Consider applying our Carnot heat engine approach to a biological system,
specifically, a hunting cheetah. The work output may be considered to be the
kinetic energy change as the 45 kg cheetah accelerates from rest to 27 m/s. The
heat input, Qus may be considered to come from the digestion of meat. The
outside temperature is 30°C and the cheetah's internal temperature from which the
Qu comes from is 42°C. Determine
b. the heat that must be rejected
c. the kilograms of meat that must be digested if 200 kJ of heat is released
for every kilogram of meat digested
