Question: This hypodermic syringe needs to eject medication at a flow speed of 12.2 m/s into the air, horizontally. (a) Let's assume that the area A

This hypodermic syringe needs to eject medication at a flow speed of 12.2 m/s into the air, horizontally. (a) Let's assume that the area A₁ of the barrel is 1000 times greater than the area A2 of the needle. What is the flow speed at A₁? (b) What is the pressure P₁? (c) Since the extra pressure (above atmospheric) at P₁ is due to the external force F acting on the plunger, what force F is needed to produce this flow speed? (Take A₁ = 2.7 x 10¯5 m².)

syringe is Carp L FO P₁ A₁ Aq 2.
