Abstract:
The objective of this experiment was to examine the pressure-flow dynamics
in a round tube coiled around a cylinder. A horizontal tube connected
to an elevated water tank allowed water to flow past a liquid monometer
and through a coiled tube. Three liquids, water, 10% sucrose, and
20 % sucrose, were allowed to flow through the tube wrapped around cylinders
with diameters of 0.288, 0.2878, and 0.110 meters. A graph of the
?P (the difference between the pressures at either end of the tube) versus
the flow rate, Q, showed a linear relationship where Q increases as ?P
increases. A graph of the Euler number versus the 1/DeanNumber2 also
showed a linear relationship where two different linear regression trends
lines existed for each solution when only one should have existed due to
the dimensionless variables that were plotted. After analysis, it
was found that these two linear regressions were not significantly different
with 95% confidence. Thus it was determined experimentally that the
Dean number is a dimensionless number that is not affected by varying solutions
or diameters of curvature. This also held true for the Reynolds number.
