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

A piston pushes liquid through a wide tube that narrows to a small outlet nozzle, with fluid emerging from the right end.
