Normal in this context means that 95 percent of the healthy population is within that range, which implies that about 2.5 percent of healthy people will have a white blood cell count over 11,000.

All stock gears are made in accordance with the diametral. pitch system. The diametral pitch of a gear is the number of. teeth in the gear for each inch of pitch diameter. Therefore, the. diametral pitch determines the size of the gear tooth.
For example, a number 40 chain would have a pitch of four-eighths of an inch, or 1/2, and would be of the standard dimensions in width, roller diameter, etc. The roller diameter is nearest binary fraction (32nd of an inch) to 5/8ths of the pitch; pin diameter is half of roller diameter.or example, a number 40 chain would have a pitch of four-eighths of an inch, or 1/2, and would be of the standard dimensions in width, roller diameter, etc. The roller diameter is nearest binary fraction (32nd of an inch) to 5/8ths of the pitch; pin diameter is half of roller diameter.
