Discharge per unit width (q) is given by
q = V1 × y1
Substituting V1 from the above equation, we get
V1 = Fr1√gy1
Now, we know that, critical depth for rectangular channel is given by
Putting q from equation 2 in the above equation, we get yc as
Putting Fr1 as 2.5 in the above equation, we get
yc = (2.5)2/3 × y1 = 1.84 × y1
