Textbook Question
Chapter 17, Problem 16RQ
Capillary action draws liquid up a narrow tube against the force of gravity as a result of surface tension. The height the liquid moves up the tube depends on the radius of the tube. The following data were collected for water in a glass tube in air at sea level.
- a. Create a proper plot of the height (H, ordinate) versus the radius (r) assuming the data are experimental.
- b. Use polyflt to determine a power relationship for the data set and graph the resulting trendline along with the experimental data.
- c. In a different experiment with different data, you determine the relationship to be H = 0.25 r–1. Create a proper plot of this expression on the same graph, assuming the units for both the radius and height are centimeters.

. I am planning to perform some volume-flow rate measurements in the Fluid Mechanics
Laboratory. For this, I need a volumetric measuring tank (graduated cylinder) and a
stopwatch. I considered the volume of the measured tank as 15 gallons and a stopwatch
with reaction time as 1/10th of a second (though resolution of 1/1000th of a second). What is
the volume flow rate if it takes 5 minutes to fill a 15-gallon of tank? Determine the smallest
division to be on the tank in order to estimate the volume flow rate within an accuracy of ±
0.05 gpm.

The drag force acting on a car is determined experimentally by placing the car in a wind tunnel. The air speed inside the tunnel is changed, and the drag force acting on the car is measured. For a given car, the experimental data generally is represented by a single coefficient that is called drag coefficient. It is defined by the following relationship: F, where air resistance for a car that has a listed C, = drag coefficient (unitless) measured drag force (N) drag coefficient of 0.4 and width of 190 cm and height of 145 cm.
