Law Laplace

[Physiology | Cardiology | Heart Health] Is a nonlinear partial differential equation that describes the capillary pressure difference sustained across the interface between two static fluids, such as water and air, due to the phenomenon of surface tension or wall tension, although usage on the latter is only applicable if assuming that the wall is very thin.

P = pressure: returned in units of mmHg

H = wall Thickness: in units of cm

T= wall tension: in units of mmHg

r = chamber radius: in units of cm
