Chapter 3 Fluid Statics: Definitions Statics: ∑F = 0. In statics we have only pressure as surface force and weight as body force. Thus‚ when fluids are still‚ the pressure is balanced by the fluid weight. No relative motion between adjacent fluid layers. Shear stress is zero Only _______ can be acting on fluid surfaces Gravity force acts on the fluid (____ force) Applications: Pressure variation within a reservoir Forces on submerged surfaces Buoyant forces 9/4/2013 1 Pressure Pressure is defined

negligible loses‚ 3 standard flanged 90 smooth elbows (KL = 0.3 each)‚ and a sharp-edged exit (KL = 1.0). We choose points 1 and 2 at the free surfaces of the river and the tank‚ respectively. We note that the fluid at both points is open to the atmosphere (and thus P1 = P2 = Patm)‚ and the fluid velocity is 6 ft/s at point 1 and zero at point 2 (V1 = 6 ft/s and V2 =0). We take the free surface of the river as the reference level (z1 = 0). Then the energy equation for a control volume between these two

MEASURING AND MODELLING HYDRAULIC FLUID DYNAMICS AT HIGH PRESSURE - ACCURATE AND SIMPLE APPROACH. International Journal Of Fluid Power‚ 13(2)‚ 51-59. ASTRACT: Dynamic properties of hydraulic fluids have to be taken into account in ever increasing fluid power applications. The main reasons are increasing accuracy demands in control and modeling‚ as well as increasing operating pressure and temperature ranges. Moreover‚ the already wide spectrum of different hydraulic fluids is also expanding all the time

Lecture No. 5 CLASSIFICATION OF FLUID FLOW AND THE CONTINUITY EQUATION 5.1 Classification of Fluid Flow Uniform flow If the velocity of the fluid is the same in magnitude and direction at every point in the fluid the flow is said to be uniform. Non-uniform flow A non-uniform flow is one where the velocities at different points at a given instant are not the same. Every fluid that flows near a solid boundary will be non-uniform because the fluid at the boundary takes the velocity of the

The increase in mosaics in churches in Late Antiquity and the Byzantine Era was largely due to the influence of the Roman Emperor Constantine (ruled from 306 to 337 AD). During his rule as emperor‚ Christianity became the major religion and there was a push for more buildings to house the followers of Christ. Along with the new buildings there was a need to decorate these places of worship accordingly and express the religion in a grandiose sort of way. Mosaics were generally the inexpensive and

Alterations in Fluids‚ Electrolytes‚ and Acid-Base Balance Composition & Compartment Distribution of Body Fluids ← Body fluids are distributed between the intracellular fluid (ICF) and extracellular fluid (ECF) compartments. The ICF compartment consists of fluid contained within all of the billions of cells in the body. It is the larger of the two compartments‚ containing approximately two thirds of the body water in healthy adults. ← The remaining one third of body water is in

CBE 6333‚ R. Levicky 1 Potential Flow Part I. Theoretical Background. Potential Flow. Potential flow is frictionless‚ irrotational flow. Even though all real fluids are viscous to some degree‚ if the effects of viscosity are sufficiently small then the accompanying frictional effects may be negligible. Viscous effects become negligible‚ for example‚ for flows at high Reynolds number that are dominated by convective transport of momentum. Thus potential flow is often useful for analyzing external
