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 answer sheet ): A B C D E F b. (2 points) If the graph of flowrate (Q) versus fluid height (H) were graphed on a (circle a letter on the answer sheet ) G H I J kind of plot, it would appear as a straight line.
