For Triangular Notch:
dQ/Q = (5/2) * dH/H.
For Rectangular Notch:
dQ/Q = (3/2) * dH/H.
dQ/Q = (5/2) * dH/H.
For Rectangular Notch:
dQ/Q = (3/2) * dH/H.

@Learner.
H = Height of the liquid above the apex of the notch.
k = Constant.
Q = Discharge over the notch.
H = Height of the liquid above the apex of the notch.
k = Constant.
Q = Discharge over the notch.

To calculate discharge Multiple the head error by:-
2.5(triangular notch).
1.5(rectangular notch).
2.5(triangular notch).
1.5(rectangular notch).

Just differenciate q=kh^5/2.
dq=k5/2dh-----equation(1)
Assume constant k=1
From given data dh=1%
Put above value in equation (1).
So dq=(1) *(5/2)*(1).
dq=5/2=2.5%.
dq=k5/2dh-----equation(1)
Assume constant k=1
From given data dh=1%
Put above value in equation (1).
So dq=(1) *(5/2)*(1).
dq=5/2=2.5%.

@Harsha Kalluri.
H = Height of the liquid above the apex of the notch.
k = Constant.
Q = Discharge over the notch.
H = Height of the liquid above the apex of the notch.
k = Constant.
Q = Discharge over the notch.

I want to know how the equation Q = kh^5/2 is formed? and what is k, h and Q.
Please tell me.
Please tell me.
