According to Poiseuille's law, the permeability for gas flow through a capillary is proportional to (where, μ = gas viscosity)___________________?
Correct answer: B. 1/μ
- A. μ
- B. 1/μ
- C. √μ
- D. μ2
Explanation
Poiseuille's law gives capillary flow proportional to the pressure gradient and inversely proportional to viscosity, with permeability scaling as r²/8μ. Therefore the dependence on gas viscosity is 1/μ.
