MAE 334 Lab 3 During each of the two minute heating runs, we would like the calorimeter to begin at a temperature close to ambient. Allow some cooling time between runs. After each of your first two runs (at about 75 and 100 rpm), use the data logger during cool down to obtain two minutes of data showing decreasing temperature vs. time. Between runs also inspect your individual data files (for heating and cooling) by opening them with Excel. Make sure they do not have any obvious problems. In each spreadsheet, create a new time column, apply the calibration to the thermistor data to convert it to temperature and plot temperature vs. time to be sure that you have sensible results. Fit a trend line to the data. It would be perfectly appropriate to make a few extra heating/cooling runs to gage the consistency of your data. Your final heating run should be completed at the highest crank speed (about 125 rpm). After you have recorded this heating result and saved the file, continue the crank rotation
