The system uses the standard ISO6976 to calculate the gas quality characteristics, calorific value, relative density, Wobbe index and compression factor.
Using these measurements, the device concludes an efficient gas mixture comprising five components such as methane, ethane, propane, nitrogen, and measured carbon dioxide and then employs ISO6976 to determine the gas quality characteristics of calorific value (CV), Wobbe index (WI), relative density (RD), and compression factor (Z).
2]/F2B (1)(3) Disk Footprint 2N(A+CK) (5) N(K+A)/F (3) Resource B-Tree Hash Bit Map Memory Footprint 0 (2) B Disk Footprint NK/(1/F-1) (2)(3) NC/B (4) Legend: A = address size B = disk block/cluster size C = compression factor (between 0 and 1) F = block fill factor (between 0 and 1) K = key size (total across all composite segments) N = number of key-address pairs S = bias (1-255) Notes: (1) Assumes that all blocks other than leaf blocks are in memory.
Calculation of compression factor Assuming that input words 16 bit long are used, then, since subtraction of successive words is required for the channel RLL code, two input words of a total length of 32 bits are required, Taking the example of Figure 1, for (2,7) code, there can be 5 'O's before the 1' and 7 'O's after the '1' Hence: 'O's 1 to 12 unused 31 to 20 12 words and 306 bits unused.
A digital principle ensures that, despite using a real-time data compression factor of 44:1, according to the Layer III/MPEG2 standard, the system reproduces at a high quality with the minimum of disruption.
From these measurements the device infers an effective gas mixture comprising five components: methane, ethane, propane, nitrogen, and measured carbon dioxide and then uses ISO6976 to calculate, among other things, the gas quality characteristics of calorific value (CV), Wobbe index (WI), relative density (RD), and compression factor (Z).
