Ions‚ atoms and molecules are constantly in random motion; this is mainly marked in liquids and gases as they are further apart. When there is a small amount of molecules of a substance in an area and a large number is another area and they have no barrier between them the random motion causes numbers to even up; this is called diffusion. Diffusion is when molecules move from a high concentration to a low concentration. The concentration gradient is when the concentration is different for each

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

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

Fluid intelligence reflects information processing capabilities‚ reasoning‚ and memory. It is used to evolve the ability to think clearly. For instance‚ a person who is asked to arrange a series of letters according to some rule or to memorize a set of numbers uses fluid intelligence. Although it is defined as the inmate and learning caoacity of all individuals. To my knowledge fluid intelligence is used in so many ways‚ throughout the country. It normally affect’s children during childhood and

interstitial fluid‚ and intracellular fluid are identical‚ but the quantity of each substance varies among the compartments. The most striking differences are the low protein content in interstitial fluid compared with intracellular fluid and plasma and the fact that sodium and chloride ions are largely extracellular‚ whereas most of the potassium ions (approximately 90%) are intracellular. This unequal distribution of ions results in a voltage difference across cell membranes. Extracellular fluid can be
