Question

A rectangular venturi of width \(10 \, \text{m}\) is designed to carry excess runoff. Compute the specific energy of water when discharge is \(30 \, \text{m}^3/\text{sec}\) and depth of water is \(1.5 \, \text{m}\).

• A. \(1.70 \, \text{m}\)
• B. \(2.00 \, \text{m}\)
• C. \(0.85 \, \text{m}\)
• D. \(4.80 \, \text{m}\)

Hint:

Specific energy equation: \[ \boxed{ E = y + \frac{V^2}{2g} } \] For rectangular channels: \[ \boxed{ V = \frac{Q}{by} } \]

Answer 1

The Correct Option is A
