WebWhat is β (Beta) of a Transistor? β (beta) of a transistor is the gain or amplification factor of a transistor. It is the factor by which current is amplified in the circuit. So if a transistor has a β of 100, the base current that goes into it is amplified by 100. WebISO 16889 (International Standard) lists eight common Beta ratios used to report filter efficiency: Beta 2, 10, 20, 75, 100, 200, 1000 and 2000. So what does each one mean and why have so many? The ISO test method involves using particle counters and test fluid that has contaminants added to it.

WebThis type of a venturi meter is generally rough cast with a pipe diameter range of 4.0–48.0 in. The throat diameter may vary quite a bit, but the ratio of the throat diameter to the main pipe diameter (d/D), also known as the beta ratio, represented by the symbol β, should range between 0.30 and 0.75.

WebDec 30, 2024 · The Beta Ratio itself is calculated by taking dividing the number of upstream particles by downstream particles. For example, if 100,000 five micron particles were measured, on average, before the filter, and 100 five micron particles were measure after the filter, the beta ratio was 1,000.
