Question 6 of 10

6. Calculate the velocity over the notch (V₁) and the velocity through the pipe (V₃) if the full supply discharge is 2 cumecs. The area of flow over the trapezoidal notch is 0.58 m². Assume the value of diameter of the pipe used as 1 m.

V₁ = 2.54 m/sec and V₃ = 3.44 m/sec

V₁ = 0.44 m/sec and V₃ = 2.04 m/sec

V₁ = 3.44 m/sec and V₃ = 3.44 m/sec

V₁ = 3.44 m/sec and V₃ = 2.54 m/sec
