To find the velocity of the flow of water, we can use the equation from gravitation laws:
Velocity Head (h) = v^2 / (2g)
where:
h = 1.25 m (given)
g = 10 m/s^2 (given)
v = velocity of the flow (to find)
Rearrange the equation for solve v
v^2 = 2gh
v^2 = 2 × 10 × 1.25
v^2 = 25
v = √25
v = 5 m/s
So, the velocity of the flow of water is 5 m/s
