The hypodermic needle in the figure below contains a saline solution. If a plunger of area A is pushed in at a steady rate ( V ), what is the mean exit velocity ( V e ) of solution leaving the needle of area A e ? Assume no leakage past the plunger. B. If there is leakage back past the plunger equal to one-third the volume ow rate from the needle, find an expression for V e . C. Neglecting leakage past the plunger, find an expression for the pressure at the face of the plunger if the uid exits the needle at atmospheric pressure...
