WebThe SI unit for surface tension is J/m 2 (or N/m). The accepted value of the surface tension of water in air at 20 o C is γ = 0.073 J/m 2. However, you must use pure water and extremely clean glass to get this result. Usually, the measured surface tension is at least half of this number. WebCapillary refill time (CRT) in adult patients has found its way into modern medical practice in a seemingly haphazard way. Introduced by Beecher et al1 in 1947, it was defined as “normal”, “definite slowing” and “very sluggish”, correlating with “no”, “slight”/“moderate” and “severe” shock, respectively.
