WebMar 5, 2024 · The Beta Ratio for Bottom Filter B is given by Beta = 200/1 = 200, which is a more efficient value. Next, we use the following equation to determine the efficiency value of a filter, known as Beta Efficiency. Beta Efficiency = (Number of upstream particles) minus (Number of downstream particles), all divided by (Number of upstream particles), WebCalculate theta / beta ratio is : 5.74 Periodic Impacts on Band Ratio Measures ¶ Typical investigations involving band ratios compare differences in band ratio measures within and between subjects. The typical interpretation of band ratio measures is that they relate to the relative power between two bands.
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.
