A method and apparatus is provided for correcting the airflow in a combustion engine drawn in through an induction pipe and measured in the induction pipe. The measured airflow is multiplied by a correction factor which is formed as a function of a value expressing the degree of the ...
What unit is air pressure measured in?Air Pressure:Air pressure is the weight of the air pushing against a particular area. While we may not think much about air having weight, the gravitational force of the Earth still acts on the atoms of the gases in the atmosphere, pulling them toward...
Using this method to measure airflow provides a very accurate reading at virtually any airspeed, even if there is no airflow at all. Since the wave travels across the entire cross section of the measured area, there is no need to transverse the area with an ultrasonic flowmeter. The sensor...
The cooling capacity of an AC is measured in tonnage. A 2-Ton AC has more cooling capacity than a 1.5 Ton AC. You should consider the room size to determine how much cooling capacity you need. A 1 Ton AC would be enough for a small room. So, choose the suitable unit with appropriat...
* The noise level (dBA) provide is determined as a value measured at our standard measurement location in an anechoic room condition (20 dBA or less) with a dark noise environment. The value of the noise level can be depending on the measurement location and the surrounding environment. * ...
RPM, or Rotations Per Minute, is how fast a fan spins. The higher the RPM, the more air it is likely to move; however, these high speeds often come at the cost of noise, measured in decibels (dB). A fan that spins exceptionally fast is likely to have a more powerful motor and to...
Classically, the dynamic compliance is measured at points of zero flow and is defined by the equation: Cdyn =VT/(ΔPel - 4Π2 -f2·VT·I) where ΔPel is the elastic pressure change. The term 4Π2−f2·VT·I (i.e., the inertial pressure change) is generally considered as ...
There is no one-size-fits-alltype of AC. Each room needs a specific kind of unit, based on the size. The room size directly affects an AC's cooling capacity. An AC's cooling capacity is measured in tonnage. For example, a 2-ton AC has a greater cooling capacity than a 1-ton AC...
Inline exhaust fans are measured by CFM (cubic feet/minute), so you need a fan that has a CFM higher than the number you figured out in the last step. However, not all CFMs are equal. If something is listed as a “Booster” fan, it typically is no nearly as strong as an inline...
A diagnostic method for an internal combustion engine determines airflow using three independent airflow determinations. The three airflow determinations are compared to each other and an error is est
