The rate  of flow of water through the open hole is 12.6\times10^-^6m^3/s.

Explanation:

Given the crossectional area of the small hole, A =2mm^2=2\times10^-^6m^2.

The height of the tank, h = 2 m.

The rate of the flow of the water is given as

Q = A v

Here, v is the velocity of the water.

Velocity is given as,

v=\sqrt{2gh}

g is the acceleration due to gravity.

substitute the values, we get velocity,

v=\sqrt{2\times10m/s^2\times2m}

v = 6.3 m/s.

thefore,

Q=2\times10^-^6m^2\times6.3m/s

Q=12.6\times10^-^6m^3/s.

Thus, the rate  of flow of water through the open hole is 12.6\times10^-^6m^3/s.
