A substance with viscosity equals 1.5 x 10-3 Pa s is filled with a sterile syringe. The syringe's nozzle area is 8.0 x 10-5 m2, and the needle length is 0.025 m. The needle has an internal radius of 4.0 x 10-4 m. The pressure of the indicator in the inserted vein is 1900 Pa (14 mm of mercury). What force must be applied to the plunger, so that 1.0 x 10-6 m3 of solution can be injected in 4.0 s?
