A hypodermic syringe is filled with a solution whose viscosity is 3.5 x 10^3 Pa.s. the plunger cross-sectional area is 12.0 x 10^-5 m^2, and the length of the needle is 0.03m. The internal radius of the needle is 6.5 x 10^-4 m. the pressure in the vein is known as 1850 Pa. what force must be applied to the plunger, so that 1.5 x 10^-6 m^3 of solution can be injected in 5.0 s?
