Consider linear flow through a cylindrical core with cross sectional areaequal to 39.458 cm2 and a length equal to L. Assume that we can model the flow asthrough a bundle of capillary tubes of two different sizes. Specifically, assume that thereare ten million capillary tubes of radius 5 micrometers and 200,000 capillary tubes ofradius 10 micrometers.
(a) Estimate the permeability in Darcies of the core using this model.
(b) Estimate the porosity of the core using this model.
