Based on the position of point 2 in the figure, applying the Bernoulli equation between points 1 and 2 is as follows.

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

Here, P1 and P2 are atmospheric pressure (P1=P2=0), and V1 is treated as 0 assuming that the water surface is wide.

Therefore, the above equation becomes  h = V2^2/2g and V2 = (2gh)^(1/2)

V2 = C*(2*g*h)^(1/2)

C : a coefficient of head loss at the exit (point 2)
