In the syringe as shown in the figure, the drug has 900 kg/m3 and an absolute viscosity μ = 0.002 Pa – s. Neglecting head loss in the larger cylinder. Determine the value of the Reynolds number for a flow of 0.4 mL/sec. through the needle. Determine the force required to produce a flow of 0.4 mL/sec.
