 Modeled our Capstone project- time to heat a Zirconium Billet to degrees farenheit  Used 1 st Term Approximation  Compared to experimental measurements

 First we assumed an infinite cylinder, in order to neglect end effects.  Solved for the h value ◦ h=405  Found the Biot number to be too high for lumped capacitance (lumped capacitance method gave t=35.75 seconds)  Used 1 st term approximation to solve for time  Found t to be 84 seconds, with Fo=

 Found time to heat to be 84 seconds  50 seconds was the measured experimental time  Accuracy was 68%

 Compare these results with Concentric Cylinders values (another group project)  Determine end effects ( )  Examine changes in start temperature of billet (i.e. changes in seasonal temperatures- winter to summer)
