Discharge considering Approach Velocity

Go Francis Discharge = (2/3)*Coefficient of Discharge*sqrt(2*Acceleration due to Gravity)*(Length of Weir Crest-0.1*Number of End Contraction*Still Water Head)*(Still Water Head^(3/2)-Velocity Head^(3/2))

Discharge Passing over Weir considering Velocity

Go Francis Discharge with Suppressed End = (2/3)*Coefficient of Discharge*sqrt(2*Acceleration due to Gravity)*Length of Weir Crest*((Height of Water above Crest of Weir+Velocity Head)^(3/2)-Velocity Head^(3/2))

Discharge over Weir without considering Velocity

Go Francis Discharge with Suppressed End = (2/3)*Coefficient of Discharge*sqrt(2*Acceleration due to Gravity)*Length of Weir Crest*Height of Water above Crest of Weir^(3/2)

Discharge for Notch which is to be Calibrated

Go Francis Discharge with Suppressed End = Constant of Flow*Height of Water above Crest of Weir^Number of End Contraction

Discharge when End Contractions is suppressed and Velocity is considered

Go Francis Discharge with Suppressed End = 1.84*Length of Weir Crest*(Still Water Head^(3/2)-Velocity Head^(3/2))

Discharge given Velocity Approach

Go Discharge by Approach Velocity = Velocity of Flow 1*(Width of Channel1*Depth of Flow)

Discharge when End Contractions is suppressed and Velocity is not considered

Go Francis Discharge with Suppressed End = 1.84*Length of Weir Crest*Height of Water above Crest of Weir^(3/2)

Discharge for Notch which is to be Calibrated Formula

Francis Discharge with Suppressed End = Constant of Flow*Height of Water above Crest of Weir^Number of End Contraction
Q_Fr' = k_Flow*S_w^n
