A/
blood pressure
p = 120/80 mmHg = 15999 Pa
force against end of syringe
F = p*A = 15999Pa * π(0.00500m)²/4 = 0.314 N
B/
Q = V / t = 2.5mL / 5s = 0.5 mL/s = 0.5 cm³/s
Then velocity
v = Q / A = 0.5cm³/s / (π(0.032cm)²/4) = 622 cm/s
or 6.22 m/s

What is the minimum force the nurse needs to apply to the syringe? Express your answer with the appropriate units. Review A 5.00 mL syringe has an inner diameter of 4.50 mm, a needie inner diameter of 0.250 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 0.212 N Correct Significant Figures Feedback: Your answer 0.211 N was eilther...
