The discharge over a triangular notch can be written as
Q = (8/15) Cd (2g)0.5 tan(θ/2) H5/2
If an error of 1% in measuring H is introduced determine the corresponding error in the computed discharge.
A right angled triangular notch is used for gauging the flow of a laboratory flume. If the coefficient of discharge of the notch is 0.593 and an error of 2 mm is suspected in observing the head, find the percentage error in computing an estimated discharge of 20 L/s.
