(A) Plot of minimum transmural pressure Pt,min versus spacing h of vessels and drainage channel. (B) Plot of Pt,min versus a normalized ratio of hydraulic conductivities hLP/K. All models had N = 4, D = 100 μm, L = 1 cm, Pin − Pout = 10 cm H2O, and Pout − Pdr = 20 cm H2O. In (A) and (B), K = 10−12, 10−11, 10−10, 10−9, or 10−8 cm4/dyn·s, and LP = 10−11, 10−10, or 10−9 cm3/dyn·s. Red plot indicates data from Fig. 3C.
