WebResistance is how hard the vessel is trying to stop the flow of fluid. It's made up of how small the vessel is, and the friction along the sides. Flow is the amount of fluid that's passing through the vessel over an amount of time. It's determined by how much the pressure can push against the resistance. ( 4 votes) WebThe left end of the tube is at a high pressure and the right end is at a lower pressure (consider the fluid moving from left to right). According to continuity, Φ 1 = flow rate 1 = Φ 2 = flow rate 2. or. A 1 v 1 = A 2 v 2. where A and v are the cross sectional area and velocity respectively. Now consider the a disease/condition where the ...

WebHagen–Poiseuille equation. In nonideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, is a physical law that gives the pressure drop in an incompressible and Newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section. WebSep 9, 2024 · Flow is the movement of volume per unit of time. Flow is affected by the pressure gradient and the resistance fluid encounters between 2 points. Vascular resistance is the opposition to flow, which is caused primarily by blood friction against vessel walls. Vascular resistance is directly related to the diameter of the vessel (smaller vessels ...
