1 Size-Tornadoes can vary widely in size. 2  A typical tornado in the United States is around 500 feet across, but some may be as narrow as just a few feet across or as large as a mile wide. 3  Wind Speed-The wind speed of a tornado can vary from 65 to 250 miles per hour.
It is always used in conjunction with a means to determine at what pressure blood flow is just starting, and at what pressure it is unimpeded. Manual sphygmomanometers are used in conjunction with a stethoscope. The word comes from the Greek ÏÏÏÎ³Î¼ÏÏ (sphygmos, pulse), plus the scientific term manometer (pressure meter).
Function. The Consistometer is a low cost, durable, instrument for accurately checking laboratory or production samples against consistency, viscosity or flow rate standards. It uses little bench space and is yet probably the simplest, most accurate method of conducting a variety of flow associated tests.he consistometer provides a single parameter for a variety of flow tests which can be carried out over any period under as near identical conditions as possible. The Consistometer or Bostwick Consistometer is manufactured from stainless steel engraved with a series of precise graduations at 0.5 cm intervals.
