Laminar flow Laminar Flow. The resistance to flow in a liquid can be characterized in terms of the viscosity of the fluid if the flow is smooth. In the case of a moving plate in a liquid, it is found that there is a layer or lamina which moves with the plate, and a layer which is essentially stationary if it is next to a stationary plate.

Resistance The resistance to the flow of charge in an electric circuit is analogous to the frictional effects between water and the pipe surfaces as well as the resistance offered by obstacles that are present in its path. It is this resistance that hinders the water flow and reduces both its flow rate and its drift speed.

- Viscosity is defined as. the resistance to flow! Viscosity of often referred to as the thickness of a fluid. You can think of water (low viscosity) and honey (high viscosity). However, this definition can be confusing when we are looking at fluids with different densities.

Sulfite Sulfites or sulphites are compounds that contain the sulfite ion SO 3 2− . The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, its salts are widely used.Sulfites are substances that naturally occur in some foods and the human body. They are also used as regulated food additives.hey may come in various forms, such as: 1  Sulfur dioxide, which is not a sulfite, but a closely related chemical oxide. 2  Potassium bisulfite or potassium metabisulfite. 3  Sodium bisulfite, sodium metabisulfite or sodium sulfite.

Fluid Mechanics: What is Poiseuille's equation and how to compare it with Ohm's law? Hagen-Poiseuille equation relates the flow rate (for the laminar flow of a Newtonian fluid) of a fluid in a pipe with the pressure drop across it just the way Ohms law relates current flowing through a wire with the Potential difference across it.

Blood Flow, Blood Pressure, and Resistance Blood flow is the movement of blood through a vessel, tissue, or organ. The slowing or blocking of blood flow is called resistance. Blood pressure is the force that blood exerts upon the walls of the blood vessels or chambers of the heart.

Poiseuille's law Poiseuille's law. the law that the velocity of a liquid flowing through a capillary is directly proportional to the pressure of the liquid and the fourth power of the radius of the capillary and is inversely proportional to the viscosity of the liquid and the length of the capillary.

- Resistors restrict or limit the flow of current in a circuit. The ability of a material or component to resist current flow is measured in ohms [ohm: Units of electrical resistance (R). 1 volt will force a current of 1 amp through a resistance of 1 ohm.

Physiology of Circulation Resistance is a force that opposes the flow of a fluid. In blood vessels, most of the resistance is due to vessel diameter. As vessel diameter decreases, the resistance increases and blood flow decreases. Very little pressure remains by the time blood leaves the capillaries and enters the venules.

- Resisitive pressure; “Ohmic Resistance”. Elastic pressure. As soon as the flow stops, airway resistance falls and the pressure – formerly required to push air through the. airway- drops to a plateau. Difference between this plateau and the peak pressure therefore must be the. AIRWAY RESISTANCE, or “Ohmic resistance”, or “flow-dependent resistance”.

Viscosity 1 Viscosity is another type of bulk property defined as a liquid’s resistance to flow. When the intermolecular forces of attraction are strong within a liquid, there is a larger viscosity. 2  Viscosity can be not only a fluid’s resistance to flow but also a gas’ resistance to flow, change shape or movement. The opposite of viscosity is fluidity which measures the ease of flow while liquids such as motor oil or honey which are “sluggish” and high in viscosity are known as viscous.

- This rests upon the Poiseuille equation, which demonstrates that resistance to flow of gas through a tube is directly proportional to length, while being inversely proportional to the radius of the tube to the fourth power (when flow is laminar).

Hydraulic Resistance In order to define the local hydraulic resistance (δP1) the Weisbach formula is used. (3) where ζ is the coefficient of local resistance. For flow in smooth channels the friction factor f depends on the flow conditions and is only a function of Re = ūDH/ν.

- Resistance refers to the property of a substance that impedes the flow of electric current. Some substances resist current flow more than others. If a substance offers very high resistance to current flow it is called an insulator. If its resistance to current flow is very low, it is called a conductor. Resistivity refers to the ability of substances to resist current flow. Good conductors have low resistivity and insulators have high resistivity.

Pump Flow The pressure rating of a pump defines how much resistance it can handle or overcome. It is usually given in bar or psi (pounds per square inch). Pressure, in conjunction with flow rate and power, is used to describe pump performance.

General Electronics Resistance is the amount of opposition to electrical current. This can be likened to the diameter of a pipe resisting the flow of drainage from the bathtub. The larger the pipe (lower resistance) the faster gravity can pull the water out of the bathtub.
