Relative enrichment of ions mediated by the leaks. (A) Comparison of steady state ion density in the lumens of various sizes with the expected concentration ($\delta {\rho }_i$). ${\xi }_i=0.1$ for all curves. For curve 1, ${\xi }_v=0.1$; curve 2, ${\xi }_v=0.2$; and curve 3, ${\xi }_v=0.5$. (B) Comparison of the lumen osmotic pressure to the Laplace pressure as a function of lumen size for different screening lengths.
