A 4.50 mL syringe has an inner diameter of 4.00 millimeter, a needle inner diameter of 0.260 millimeter, and a plunger pad diameter (where you place your finger) of 1.2 centimeter. A nurse uses the syringe to inject drug into a patient whose blood pressure is 140/100.
Find the minimum force the nurse needs to apply to the syringe?
The nurse empties the syringe in 2.70 second. Find the flow speed of the drug through the needle?
