Q- A hypodermic syringe is attached to a needle that has an inner radius of 0.305 mm and a length of 3.00 cm. The needle is field with a solution of viscosity 2.01*10-3 Pa.s. It is injected in to a vein at a gauge pressure of 16.6 mm of Hg.
(a) What must the pressure of the fluid in the syringe be to inject the solution at a rate of 0.252 mL/s?
(b) What force must be applied to the plunger which has an area of 1.03 cm2?
