v = ψ ( 2 g H )^{0.5}

s = 2 ( h H )^{0.5}

V = ψ ε A ( 2 g H )^{0.5}

F = V · v · ρ

Where:

v = Discharge velocity (m/s),

s =
Discharge velocity without any coefficient of friction (m/s),

V = Volume of reaction (m^{3}/sec),

A = Area of discharge opening (m^{2}),

H = Depth (m),

g = Acceleration due to gravity (9.81 m/s) ,

ψ = Coeffcient of friction (for water ψ = 0.97),

ε = Coeffcient of contraction (ε = 0.62 for sharp edged openings and ε = 0.97 for smooth rounded openings),

ρ = Density (kg/m^{3}) (water = 997 kg/m^{3})

F = Force of reaction (N)
