basis method for pulp chips and fuel, where it is used for a one-time point estimate of what fraction of the whole is usable fiber (or fuel) and what fraction is wa-ter. As you will note, in the example provided above, the OD basis moisture content can (and will) exceed 100% on occasion â this is NOT an error â it simply re-
Shapers spin slower than routers, usually in the 7-14,000 rpm area and their power demand starts where routers leave off, (around 3 HP). Router tables are welter weights by comparison. It takes two routers to equal one shaper.
Two heads, one on each side of a disk, read or write the data as the disk spins. Each read or write operation requires that data be located, which is an operation called a seek. (Data already in a disk cache, however, will be located more quickly.) A hard disk/drive unit comes with a set rotation speed varying from 4500 to 7200 rpm. Disk access time is measured in milliseconds. Although the physical location can be identified with cylinder, track, and sector locations, these are actually mapped to a logical block address that works with the larger address range on today's hard disks.
