A = 2 mm^2 \\\\ P_1 + \rho g h_1 + \frac{1}{2} \rho V_1 ^ 2 = P_2 + \rho g h_2 + \frac{1}{2} \rho V_2 ^ 2 \\\\ V_ 2 = \sqrt {2gh_2 } = \sqrt { 2 \times 10 \times 2 } = \sqrt {40} \\\\ rate \: \: of \: \: flow \: \: = AV \\\\ = (2 \times 10 ^{-6}\times \sqrt {40}) \\\\ 12.64 \times 10 ^ { -6 } m/s

 


Option 1)

12.6 \times 10 ^{-6 } m^3 / s

Option 2)

8.9 \times 10 ^{-6 } m^3 / s

Option 3)

2.23 \times 10 ^{-6 } m^3 / s

Option 4)
