A 90o v-notch weir is used to measure discharge flow rate. Ahead (H) of 6 inches is measured behind the weir. Assume thefollowing:
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 flowmeasurement
Please show all work. Thank you so much in advance!
