One of the most challenging problems in environmental remediation is isolated blobs of contaminated fluid that become trapped in soils by capillary forces (i.e., surface tension). The pore space can be analyzed by analogy to a thin-diameter glass tube. Under the conditions given, what is the maximum length of water, I, that can be retained in the vertical glass tube shown? [mm] • contact angle 0 = 0° • surface tension - 72 dyn/cm = 0.072 N/m • tube diameter D = 2.0 mm • neglect the small volume of water above the meniscus • the weight of water completely removes the curvature in the lower air-water interface
