WebbSolution for what is the water pressure (in kPa) just under the meniscus in the capillary tube of 0.01 mm if the surface tension of water is 73 x 10^-6 Webb2 okt. 2024 · For water and most liquids, this is the bottom of the meniscus. For mercury, take the measurement from the top of the meniscus. In either case, you are measuring …
Meniscus - brennen.caltech.edu
When reading a depth scale on the side of an instrument filled with liquid, such as a water level device, the meniscus must be taken into account in order to obtain an accurate measurement. Depth must be measured with the meniscus at eye level (to eliminate parallax error) and at the center of the meniscus, i.e. the … Visa mer The meniscus (plural: menisci, from the Greek for "crescent") is the curve in the upper surface of a liquid close to the surface of the container or another object, produced by surface tension. A concave meniscus … Visa mer Menisci are a manifestation of capillary action, by which either surface adhesion pulls a liquid up to form a concave meniscus, or internal cohesion pulls the liquid down to form a convex meniscus. This phenomenon is important in transpirational pull in … Visa mer The formation of menisci is commonly used in surface science to measure contact angles and surface tension. In a contact angle … Visa mer • Using menisci to measure surface tension Visa mer Webb19 okt. 2024 · Pressure 2. Flow 3. Shape 4. Volume Answer : 3.

To what height would water rise in a glass capillary tube of 0.01 …
Webb14 apr. 2024 · In addition, the study of apparent viscosity and shear rate of non-Newtonian fluid shows that the increasing and decreasing trends of flow rate and shear rate and the changing trends of flow rate and pressure gradient are consistent, and shear rate can be used to describe the characteristics of fluid instead of the pressure gradient. WebbThe pressure on the surface of water is atmospheric pressure P. The pressure just below the plane surface of water outside the tube is also P, but that just below the meniscus … Webb26 nov. 2024 · As the meniscus is concave and nearly spherical, the pressure below the meniscus will be (p o – 2T/r) where r is the radius of the meniscus. This is the condition … c.d. peacock oak brook
