Test: Flow Through Open Channels - 2 - Question 1

A right-angled triangular channel symmetrical in section about the vertical carries a discharge of 5 m3/s with a velocity of 1.25 m/s. What is the approximate value of the Froude number of the flow?

Detailed Solution for Test: Flow Through Open Channels - 2 - Question 1

We know that,
Q = AV
⇒ 5 = A x 1.25 ⇒ A = 4 m2
For a symmetrical right angled triangular channel,
m = 1
∴ A = my2 = 1 x y2 = y2
T = 2my = 2 x 1 x y = 2y
But A = 4 m2
⇒ y2 = 4   ⇒ y = 2 m

A rectangular channel is 6 m wide and discharges 30 m3s-1. The upstream depth is 2.0 m, acceleration due to gravity is 10 ms-2. Then, what is the specific energy (approximate)?
Detailed Solution for Test: Flow Through Open Channels - 2 - Question 5

We know that, 
Q = AV

⇒ 30 = 6 x 2 x V
⇒  \/ = 2.5 m/s
The specific energy may be given as,

For a smooth hump in a subcritical flow to function as a broad crested weir, the height ΔZ of the hump above the bed must satisfy which one of the following?
(E1 = Specific head upstream of the hump, Ec = Specific head at the critical" depth yc) (Neglect friction effects)
Detailed Solution for Test: Flow Through Open Channels - 2 - Question 7

If the flow is subcritical, then after the introduction of hump the specific energy will decrease by ΔZ (height of hump).
E0 ≤  E1 - ΔZ 
⇒ ΔZ ≤ (E1 - E0)
