Question

A small hole of area of cross-section \(2 mm^2\) is present near the bottom of a fully filled open tank of height \(2 m\). Taking \(g=10 m/s2\), the rate of flow of water through the open hole would be nearly:

• A. \(12.6 \times 10^{-6} m^3/s \)
• B. \(8.9 \times 10^{-6} m^3/s \)
• C. \(2.23\times 10^{-6} m^3/s \)
• D. \(6.4 \times 10^{-6} m^3/s \)

Answer 1

The Correct Option is A

The correct option is (A) :\(12.6 \times 10^{-6} m^3/s \)
