In discharge over V-notch experiment, calibration curve (using log Q vs log H) is plotted. How would you interpret results which, when plotted logarithmically, fall on a line which is not straight but slightly curved? and, What are the effects of a change in the V-notch angle on the discharge equation and the accuracy of flow measurement?

A 90o v-notch weir is used to measure discharge flow rate. A head (H) of 6 inches is measured behind the weir. Assume the following: Weir equation is Q = 2.5H2.5 (Q in cfs and H in feet) 1 cfs = 450 gpm a) Estimate discharge flow rate in gallons per minute (gpm) b) Briefly describe hydraulic principle of open channel flow measurement Please show all work. Thank you so much in advance!

For both resistances, plot the discharge curve of ln(V/V0) vs. time. From the slope of the line, calculate C (capacity). Please explain in detail how to plot/determine some of the values of ln(V/V0), how to determine the slope of the graph, and if possible demonstrate using Excel. Thank you.

The demand curve for grilled cheese sandwiches has been estimated using statistical techniques as follows: log(Q) = -1.10 - 0.18log(P) + 1.21log(I) + 0.84log(Ph) where Q is the quantity of grilled cheese sandwiches P is the price of grilled cheese sandwiches I is income Ph is the price of hamburgers. Thats all information a. If P = $1,000, calculate the price elasticity of demand b. Draw the Engel curve. (just show the shape, don’t need to show specific point) c....
