Problem #13
For questions 1 3:
indicate which graph, shown below, would BEST match the function described (Choices A – F)
indicate which type of graph would be used to make the data appear linear from Choices G – J
below
(G)Linear plot, both axis as linear
(H)Semilogarithmic plot, abscissa (x) axis logarithmic
(I) Semilogarithmic plot, ordinate (y) axis logarithmic
(J) Loglog plot, both axes logarithmic
NOTE!!
The origin is in the lower left of each graph except for Graph A.

Problem #1
Weirs are used to determine discharge flowrate and are typically installed in open channels such as
streams.
A Cipoletti weir is described by the following equation, where Q is flowrate, L is length, and H
is height:
a.
(2 points)
If the length is constant, then the graph of flowrate (Q) as a function of fluid height
(H) looks like graph (circle a letter on the
