Mechanical Properties of Fluids

A small hole of cross-sectional area 2 mm $^{2}$ is present near the bottom of a fully filled open tank of height 2 m. Taking $g = 10 m/ s^{2}$ , the rate of flow of water through the open hole would be nearly:

A. $12.6 \times 1 0^{- 6} m^{3} /s$ ✓
B. $8.9 \times 1 0^{- 6} m^{3} /s$
C. $2.23 \times 1 0^{- 6} m^{3} /s$
D. $6.4 \times 1 0^{- 6} m^{3} /s$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
