Question

9/20/89 pm (site 2) 300 200 100 a channel center cross section a flow margins cottonwood -100 -200 300 -200 -100 100 200 east

Note that the scales are in feet, not meters!! The cross sectional profile is shown below. "I" represents the instrument location, at (0,0).

For each of the two sites:

1. Estimate the radius of curvature, r, of the channel through this bend; report it in meters: __________.

Note: You can do this by plotting the Northing and Eastings as y,x points on a plot, and using a compass to best-fit a curve through the plotted points. Make sure that both the N and E axes of the plot have the same scale.

2. Estimate the slope of the flow surface as it went around the bend,

Wednesday's laboratory expernnent attempts to verify Ohm's Law and measure the resistance (R) of a resister Ammeters and voltmeters potentially have offsets, resulting in a constant added to the equation: V = IR + VO If voltage satisfying this equation is plotted against current, the result is a line.
