From Bernoulli equation, energy conditions between Point 1 and Point 2 are same and can be expressed as follow:

V1^2/(2g) + P1/(¥ñg) + h = V2^2/(2g) + P2/(¥ñg) + 0

if P1=P2 and V1=0, above equation can be written as follow:

V2 = C*(2gh)^(1/2)

V2 : average velocity of flow (m/s)
C : velocity coefficient (= actual velocity / theoretical velocity)
g : gravity acceleration (m/s^2)
h : height between Point 1 and Point 2 (m)
