Answer published by the source. Consult the official source to check your work against its answer.
question
The discharge coefficient of a right-angled weir is to be determined over a range of values of upstream head h. To calibrate the weir, the discharge from the weir was collected in a tank and weighed over a clocked time interval. This procedure resulted in the following measurement of volume flow rate versus upstream head. Q (cfm) h (inches) 0.30 1.73 4.73 9.70 16.0 26.2 39.2 54.2 73.1 94.8 1 2 3 4 5 6 7 8 9 10 From the preceding data, calculate discharge coefficient versus h. For a right-angled triangular weir, the ideal discharge rate is Q_i= (8/15)\surd(2g) h^5/2
