How to Calculate and Solve for Discharge of a Ventruiflume | Methods of Application of Water

The image above represents discharge of a ventruiflume. To calculate discharge of a ventruiflume, seven essential parameters are needed and these parameters are Value (C_a), a_n, Value (g), Water depth (h₁), Water depth (h₂), Cross-section area at inlet (a₁) and Cross-section area at throat portion (a₂).

The formula for calculating discharge of a ventruiflume:

Q = ^{C_aa_n√(2g(h₁ – h₂))} / _{a1² – a2²}

Where:

Q = Discharge of a Ventruiflume
C_a = Value
a_n = a_n
g = Value
h₁ = Water Depth
h₂ = Water Depth
a₁ = Cross-Section Area at Inlet
a₂ = Cross-Section Area at Throat Portion

Let’s solve an example;
Find the discharge of a ventruiflume when the value is 2, a_n is 4, value is 7, water depth is 11, water depth is 10, cross-section area at inlet is 12 and cross-section area at throat portion is 5.

This implies that;

C_a = Value = 2
a_n = a_n = 4
g = Value = 7
h₁ = Water Depth = 11
h₂ = Water Depth = 10
a₁ = Cross-Section Area at Inlet = 12
a₂ = Cross-Section Area at Throat Portion = 5

Q = ^{C_aa_n√(2g(h₁ – h₂))} / _{a1² – a2²}
Q = ^{2(4)√(2(7)(11 – 10))} / _{(12)² – (5)²}
That is, Q = ^{2(4)√(2(7)(1))} / _{(144) – (25)}
Q = ^2(4)√(14) / ₁₁₉
Q = ^2(4)(3.741) / ₁₁₉
This means Q = ^29.93 / ₁₁₉
Q = 0.25

Therefore, the discharge of a ventruiflume is 0.25.
