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