Water at 20◦C is forced from a 2.5-cm-diameter syringe through a 0.15-cm hollow needle as a result of a 0.85 N force applied to the piston, as illustrated in Figure ECP 4.60. The final position of the top of the piston at point 1 is 3.6 cm below the tip of the needle at point 2. (a) Determine the ideal velocity of the forced jet as it leaves the tip of the needle at point 2. (b) Determine the ideal height of the forced jet trajectory at point 3.
