WebBecause flowing blood has mass and velocity, it has kinetic energy (KE).This KE is proportionate to the mean velocity squared (V 2; from KE = ½ mV 2).As the blood flows inside a vessel, pressure is exerted laterally … WebThe total blood flow in series, Q, is equal across all parts of the system. Individual vessels in the parallel system have different Qs, since the blood flow is split between each of …
WebThe rate of mean blood flow depends on both blood pressure and the resistance to flow presented by the blood vessels. Mean blood pressure decreases as the circulating blood … WebApr 14, 2024 · Two equations exist for estimating blood volume given the gender, height (H), and weight (W) of the patient. The Nadler equation is built upon the work of Dr. Allen in 1962, while the Lemmens-Bernstein-Brodsky equation is more accurate for higher ranges of body weight and body mass indices in patients without critical illnesses.
WebJul 29, 2024 · Assuming blood is a Newtonian fluid which is governed by the Navier-Stokes equations and continuity equation and with making use of the Navier-Stokes equation, a simple differential equation called as the circulatory system equation is derived.
