Gentlemen, please check and help me with question #3

Tank filled with water and orifice diameter of 3 cm in the bottom. Height between centre of orifice and water level 3 m. Coefficient of discharge - 0.64, coefficient of velocity- 0.97. 

Find:

1. Actual jet velocity? This one I know how to do.

V(actual) = square root from 2gH

2. Jet diameter? This one I know as well.

Coefficient of contraction= coefficient of discharge/ coefficient of velocity 

Diam of jet we will find from formula:

Coefficient of contraction = (diameter of jet/diameter of orifice)^2

3. How long will it take for jet to be established?
