Without more detail or a diagram it is impossible to given an answer to this question. It probably needs the application of Bernoulli's principle and the equation of continuity. http://en.wikipedia.org/wiki/Bernoulli%27s_principle A look at Torricelli's equation might be useful? https://www.boundless.com/physics/fluid-dynamics-and-its-applications/bernoulli-s-equation/torricelli-s-law/

Assuming there is two holes, total flow will be the sum of each flow. If only one it will be equal to a low via the smalest diameter. 

Toricelli V$$=\sqrt{2.g.h}$$

Flow     I=S.V.$$\rho$$
 where S section of each hole. 
Numerical application given

v=4,47 m/s

flow via 0.6 diam hole = f1=1.26 cbm/s
flow via 0.2 diam hole = f2=0.14 cbm/s

Total: 1.4 cbm/s
if one hole 0.14 cbm/s
