Figure below shows a liquid being pushed out of the tube by a piston having area of cross section $\displaystyle 2.0 \mathrm{~cm}^2$. The area of cross section at the outlet is $\displaystyle 10 \mathrm{~mm}^2$. If the piston is pushed at a speed of $\displaystyle 4 \mathrm{~cm} \mathrm{~s}^{-1}$, the speed of outgoing fluid is $\displaystyle \_\_\_\_$ $\displaystyle \mathrm{cm} \mathrm{s}^{-1}$
