An absorbent material is being designed to clean up a toxic liquid material. The surface tension of the toxic material is 0.028 N m−1. The absorbent material has within its structure tiny cylindrical openings that have a diameter of 0.5 mm. The cylindrical openings cover 45% of the absorbent material’s surface. The contact angle (θ) of the toxic substance and the absorbent material is such that the cos θ = 0.9105. From this information estimate the initial mass flux (grams per second per cm2 of absorbent material) of the toxic material into the absorbent material. The density of the toxic substance is 1.04 g cm⁻³.
