A 1.5 mL syringe has an inner diameter of 4.0 mm , a needle inner diameter of 0.28 mm , and a plunger pad diameter (where you place your finger) of 1.2 cm. A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100. Assume the liquid is an ideal fluid. The nurse empties the syringe in 3.9 s . What is the flow speed of the medicine through the needle?

A syringe has a fine needle with an inside diameter of 100 μm. The barrel has a diameter of 2.35 cm and is filled with water. Calculate the velocity of water as it squirts horizontally from the needle if you apply a force of 1.85 N onto the plunger. (Hint: you may approximate the area of the barrel to be much larger than the area of the needle).
