Shunt equation
WebAlveolar Gas Equation. The alveolar gas equation is a formula used to approximate the partial pressure of oxygen in the alveolus (PAO2):PAO2= (PB−PH2O)FiO2− (PaCO2÷R)where PB is the barometric pressure, PH2O is the water vapor pressure (usually 47mmHg), FiO2 is the fractional concentration of inspired oxygen, and R is the gas exchange ratio. WebThe five parameters in this equation are primary to all single diode equivalent circuit models: : light current (A) : diode reverse saturation current (A) : series resistance () : shunt resistance () : diode ideality factor (unitless) For a photovoltaic module or array comprising cells in series, and assuming all cells are identical and under ...

WebMar 3, 2024 · Types of DC Generators. DC generators are categorized into three main types based on the methods of field excitation: Permanent Magnet, Separately Excited, and Self-Excited DC generators. The first type excites the field coils by using Permanent magnets, while the separately excited one includes an external force for excitation. WebFeb 1, 2004 · The alveolar gas equation (AGE) is well known and relates the alveolar concentration of oxygen Fao2 (or equivalently partial pressure Pao2) to three variables: Fio2, Faco2 and the respiratory quotient ( R ). However, the AGE predicts an absurdity: if we input a Fio2 sufficiently low, say 0.05 ( i.e. a Pio2 of about 5 kPa), into the equation ...
