Calculating base saturation
WebApr 15, 2011 · A transistor goes into saturation when both the base-emitter and base-collector junctions are forward biased, basically. So if the collector voltage drops below the base voltage, and the emitter voltage is below the base voltage, then the transistor is in saturation. ...

WebThe proportion of acids and bases on the CEC is called the percent base saturation and can be calculated as follows: Total meq of bases on exchange sites Pct. base =(i.e., meq Ca ++ meq Mg ++ + meq K +) saturation ----- x 100 Cation exchange capacity The concept of base saturation is important, because the relative proportion of acids and bases ... WebNow let's calculate the base series resistance. This is equal to the voltage across the resistor, divided by the current through it. The current through the resistor is the same as the base current. The voltage across it is the rail …
WebApr 27, 2016 · 0. Transistors are current controlled devices that is Ic=Ib*Hfe so to give the right value to base resistor you should start from current required by pump so you will know Ic. From Ic you could define Ic= 10*Ib … WebSep 12, 2024 · When assessing the acid-base balance, most ABG analyzers measure the pH and PaCO2 directly. A derivative of the Hasselbach equation calculates the serum bicarbonate (HCO3) and base deficit or excess. This calculation frequently results in a discrepancy from the measured due to the blood CO2 unaccounted for by the equation.
WebMar 24, 2024 · The amount of acid or base required to change the charge of the soil is known as acid saturation (base saturation). To calculate CEC, divide the acid/base saturation by the soil's bulk density. The result will be the CEC, measured in meq/100g. WebMar 16, 2024 · Percent Saturation. Both Percent Nutrient Saturation and Percent Base Saturation refer to a measurement, or estimate of the percent of the soil CEC that is occupied by a particular nutrient (nutrient …
WebSoil base saturation or percent base saturation is the measurement of the proportion of soil CEC (negatively charges exchange sites) that is occupied (adsorbed) by the basic cations such as Ca 2+, Mg 2+, Na + and K +. …
