18 Ιουν 2007 · Functional capacity is the ability of an individual to perform aerobic work as defined by the maximal oxygen uptake (V̇ o 2max), that is, the product of cardiac output and arteriovenous oxygen (a−V̇ o 2) difference at physical exhaustion, as shown in the following equation:
1 Basic Laws for Material Volumes Material volumes and material particles The behavior of material systems is controlled by universal physical laws. Perhaps the most ubiquitous of these are the law of mass conservation, the laws of motion published by Isaac Newton's in 1687, and the first and second laws of thermodynamics,
1.1 Material volumes and material particles. Material systems behave according to universal physical laws. Perhaps the most ubiquitous of these are the law of mass conservation, Newton’s laws of motion, and the first and second laws of thermodynamics, all of which were understood before the nineteenth century ended.
26 Σεπ 2000 · Functional capacity, particularly when estimated rather than measured directly, is often expressed in metabolic equivalents (METs); 1 MET represents resting energy expenditure and approximates 3.5 mL O 2 · kg − 1 · min − 1.
The principal question that functional capacity assessment aims to address is ‘does this patient have the physiological reserve capacity to undergo this specific surgical procedure, without serious perioperative complications’? 1 Functional capacity is defined as the maximum (or near-maximum) physical activity that an individual is capable ...
The mass flow rate and volume flow rate are defined as the mass and volume of a fluid flowing through an inlet or outlet per unit time, respectively. They are expressed as \[\dot{\mathbb{V}}=\displaystyle\frac{d\mathbb{V}}{dt}=\dot{m}v=V_{avg,\ n}A\] \[\dot{m}=\displaystyle\frac{dm}{dt}=\rho\dot{\mathbb{V}}=\rho\ V_{avg,\ n}A\] where \[A\] \[m\]
The First Law of Thermodynamics: Control Volumes . Here we will extend the conservation of energy to systems that involve mass flow across their boundaries, control volumes. Any arbitrary region in space can be selected as control volume. There are no concrete rules for the selection of control volumes.
