WebJan 30, 2024 · What would be the height of a liquid in a column, on earth, with a liquid-air surface tension 0f .0973 N/m, contact angle of 30 degrees, density of 1200 kg/m 3? Note that the radius of the tube is 0.2 meters. What would be the height of water in a glass tube with a radius of .6mm? Solutions WebIf water gets into the lungs, the surface tension is too great and you cannot inhale. This is a severe problem in resuscitating drowning victims. A similar problem occurs in newborn infants who are born without this surfactant—their lungs are very difficult to inflate.
Determine the minimum size of glass tube that can be used to …
WebThe contact angle is the angle, conventionally measured through the liquid, where a liquid–vapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid via the Young equation. A given … WebApr 10, 2024 · Previous experiments indicated that the contact time of the impacting droplet on the superhydrophobic surface, t c, is independent of the dimensionless Weber number, W e = ρ V 2 R / γ, where ρ, V, R, and γ are the water density, impacting velocity, the radius of the droplet, and the surface tension of water in the air, respectively [44,45]. take snapshots of 5 different pokemon
