Prоblem 1. Estimаting the temperаture оf а leg in an ice bath After intense training, athletes immerse themselves in an ice bath tо treat their sore muscles. Consider an athlete’s upper leg submerged in an ice bath with a temperature of 12°C, with the following simplifications: The upper leg can be approximated as a cylinder with radius of 10 cm. The skin outer surface temperature is the same as that of the ice bath (12°C). The leg is composed of different materials (e.g. skin, muscle, bone), but we assume that it has constant properties. The thermal conductivity of the leg can be approximated by an average value of 0.6 W/m-K. The metabolic heat generation rate is slowed by the cooling, but it is still present uniformly throughout the leg at a value of 1100 W/m3. Complete the following: Starting from the most general partial differential equation for heat transfer, simplify it based on the following assumptions: a. Steady-state, b. Conduction heat transfer, c. 1-D heat transfer (r-direction only), d. Constant properties and e. Uniform volumetric heat generation within the system Write the two boundary conditions needed to solve this problem. At steady-state, find the temperature profile of the upper leg in the radial direction. Also determine the expressions for the constants (use symbols only, don’t plug in values.) Calculate the values of the constants (don’t forget their units) What is the temperature at the center of the leg at steady-state? Does your value for (5) make sense? Do you think this is possible in real life? Why or why not? What can you do to improve your analysis? (Hint: Some of the assumptions may not be valid.)
