How much time is required to inject a sample equal to 2.0% of the length of a 60 cm capillary if the diameter is 50 um and the pressure difference is 2.0x104 Pa (0.20 bar)? Assume the viscosity is 0.0010 kg/(m-s), which is close to the viscosity of water.

Question 46,
How much time is required to inject a sample equal to 2.0% of the length of a 60 cm
capillary if the diameter is 50 um and the pressure difference is 2.0x104 Pa (0.20
bar)? Assume the viscosity is 0.0010 kg/(m-s), which is close to the viscosity of water.
Note: The units work out when we realize that
Pa force/area (kg - m/s?)/m² = kg/(m-s²).
