Pressure - HyperPhysics Concepts

WebThe resistance to flow of a fluid and the resistance to the movement of an object through a fluid are usually stated in terms of the viscosity of the fluid. Experimentally, under conditions of laminar flow, the force required to move a plate at constant speed against the resistance of a fluid is proportional to the area of the plate and to the ...

WebOct 29, 2012 · Pressure vs Flow . Pressure and flow are two terms often used when dealing with fluid; that is liquids or gasses. These two properties are characteristics of the … WebIt is known that the resistance to flow through a cylindrical tube or vessel depends on several factors (described by Poiseuille) including: 1) radius, 2) length, 3) viscosity of the fluid (blood), and 4) inherent resistance to flow, as follows: where r = inside radius of the vessel, L = vessel length, and η = blood viscosity.

WebJul 22, 2024 · In a single tube (akin to local blood flow), it is quite easily to visualize to what these different terms relate. When applying it to the whole cardiovascular system, cardiac output would be flow, difference between systemic arterial pressure and central venous pressure would be the pressure gradient, and the total peripheral resistance would be … WebMar 31, 2024 · For example, our veins have very little resistance due to their ability to distend; this enables a vein’s resistance to fall in response to increasing pressure and thus keeps flow constant. Resistance is …
