ASSIGNMENT: EXPERIMENT FLOW
                                      
   Handed out: September 7

   Due: September 14 at 5 pm in 4-339B

   Problem 1: Here is a summary of the measurements, graphs, and
   calculations you were asked to perform in the lab Experiment Flow.

   a) Record room and water temperatures at the start and finish of your
   experiment.

   b) Record the length of your stirrers.

   c) On the linear graph paper, plot the level of the water above the
   hole (the "head") in mm versus the average time in seconds to reach
   that level for each of the tube lengths. (You should have three
   graphs.)

   d) On the semi-log paper, plot the head vs. average time for each of
   the tube lengths.

   e) Determine the time constants for each of your three experiments.
   Report your results in the table Time Constants for Experiment Flow
   that is attached to the problem.

   f) Make a plot of tube length vs. time constant.Is there any nice
   curve that passes through the data points? What does an extrapolation
   to zero tube length mean?
