Capillary force supports the weight of the wetting film h is the height of the capillary rise with respect to the reference level (height of liquid column in the first tube), g is the acceleration due to gravity (98 m/s 2 ), ρ is the density of the liquid, r is the radius of the tube, γ is the surface tension, θ is the contact angle of the. The capillary refill time (crt) tests blood flow and aids in the diagnosis of shock and heart disease, and is evaluated by the color change seen after applying and then releasing pressure on the gums.
