Laplace's law, all except: (A) P = T/r, (B) P = 2T/r, (C) T = Pr/W, (D) T = WP/R
Answer is D. Law of Laplace, an impoant physical principle with several other applications in physiology. This law states that tension in the wall of a cylinder (T) is equal to the product of the transmural pressure (P) and the radius (r) divided by the wall thickness (w):T = Pr/w Ref: Ganong's Review of Medical Physiology 25th Edition.
