A wire of radius R, iength L, and initial temperature T, is cooled by a fluid of
iemperature T at time t= 0. The heat transfer coefficient is h. Find the
temperature and the cooling rate of the wire as a function of time. Assume
constant thermal properties and neglect the radial temperai ure gradient ani end
effects.
