| Description: A hypodermic syringe is filled with a solution whose viscosity is 1.5×〖10〗^(−3) Pa⋅s. The plunger area of the syringe is 8.0×〖10〗^(−5) m^2, and the length of the needle is 0.025 m. The internal radius of the needle is 4.0×〖10〗^(−4) m. The gauge pressure in a vein is 1900 Pa (14 mmHg). What force must be applied to the plunger, so that 1.0×〖10〗^(−6) m^3 of solution can be injected in 3.0 s?
