a) Using the chart from step 3, estimate the dead time, L. This is the time prior to the start of the
linear increase in the temperature.
If a line approximating the linear increase in temperature has been drawn on the chart, the
deadtime is the time at which this line intersects the initial temperature. The units should be in
seconds.
In Figure 3-7, the dead time is approximately 300 seconds.
NOTE: Only an estimate of the dead time is required. An exact answer is not expected or
required.
