When a liquid is in contact with a solid, if the forces of adhesion between the molecules of the liquid and the solid are greater than the forces of cohesion among the liquid molecules themselves, the liquid molecules crowd towards the solid surface. Gaserek and J.A.Swaffirld (Longman) 2. As individual elements do not move relative to each other, shear stresses are not involved and all forces due to the pressure of the fluid are normal to the surfaces on which they acts. Hydraulics: Sciences that deals with liquid flows in pipes and open channels. Spread the love. Such poro-elasto-capillary interactions can be seen in the wrinkling of paper, swelling of cellulose sponges, and morphing of resurrection plants. Prepared by: Addisu Dagne Although, if the density of the liquid increases, the rise of the liquid in the capillary will les… Introduction to Fluid Mechanics: Relevance and significance in engineering applications, Definitions, Fluid Properties, Flow Analysis Techniques, Flow Patterns.

FLUID MECHANICS FOR. 12 Application areas of Fluid Mechanics When you think about it, almost everything on this planet either is a fluid or moves within or near a fluid. Narrower the tube, higher will the liquid rise. Academia.edu no longer supports Internet Explorer. Fluid Mechanics February, 2017. We can define capillary action as a phenomenon where ascension of liquids through a tube or cylinder takes place. Chapter 1. 5, p. 658. Objectives.

Academia.edu uses cookies to personalize content, tailor ads and improve the user experience. Knowledge of Fluid Mechanics is essential for proper design of Ships. If a segment of a capillary tube is submerged in a liquid, the liquid in the capillary tube can rise or fall. This effect is called capillarity and is caused by the surface tension. Now customize the name of a clipboard to store your clips. Dimensionless numbers in fluid mechanics are a set of dimensionless quantities that have an important role in analyzing the behavior of fluids.Common examples include the Reynolds or the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, flow speed, etc. Proteins in the plasma are normally too large to diffuse into the interstitium, however, in certain scenarios, such as in inflammation, these proteins can. MECHANICAL PROPERTIES OF FLUIDS 249 t Fig.10.3 Fluid under gravity. Mohanty, Prentice Hall of India Pvt. The main equation required for this is Newton's second law for non-accelerating bodies, i.e. Capillarity, rise or depression of a liquid in a small passage such as a tube of small cross-sectional area, like the spaces between the fibres of a towel or the openings in a porous material.

A fluid is a substance that deforms continuously when subjected to a shear stress, no matter how small that shear stress may be. CE8394 FMM Notes. Here in this video you will be getting detail about Capillarity . The rise and fall of a liquid surface in a small thin tube, when it is immersed vertically in a liquid is called capillarity (capillary action). 1 Such poro-elasto-capillary interactions can be seen in the wrinkling of paper, swelling of cellulose sponges, and morphing of resurrection plants. Journal of Applied Mechanics and Technical Physics, Vol. In this video lecture i have discussed about the definition of capillarity, capillarity rise and capillarity fall, cohesion, adhesion, difference between cohesion and adhesion and derivation on capillarity.

What is a Fluid? that of surface tension and a ratio between cohesion to adhesion increase the rise will also increase. Interstitial hydrostatic pressure: the pressure of the fluid in the interstitium. Sorry, preview is currently unavailable. The rise or fall depends on the relative magnitudes of the cohesion and the adhesion of the liquid to the walls of the capillary tube. This pressure is attempting to pull fluid into the blood. Capillarity in porous media with nanopores has received more and more attention in a variety of fields. Before your class you went to PC lab and took a print out of your assignment.
