A syringe which has an inner diameter of 0.60mm is attached to a 25-gauge needle with an inner diameter of 0.25 mm. A nurse uses the syringe to inject an ideal fluid into a patient’s artery. Assume a venous blood pressure of 2 x 103 Pa and the density of the blood is 1050 kg/m3 (10 pts)

a) What is the fluid speed (m/s) in the needle if the nurse injects 10cc in 10 sec?

b) The minimum pressure (diastolic pressure) in the artery of the patient is 100mmHg.

What minimum force must the nurse apply to the syringe?

Solutions

Expert Solution

RESULT:
