When To Call a Doctor. Call or other emergency services immediately if you have vertigo (a spinning sensation) and: 1  You passed out (lost consciousness). 2  You have symptoms of a stroke, such as:  Sudden numbness, tingling, weakness, or loss of movement in your face, arm, or leg, especially on only one side of your body.
High quality deionized water has a conductivity of about 5.5 Î¼S/m, typical drinking water in the range of 5-50 mS/m, while sea water about 5 S/m (i.e., sea water's conductivity is one million times higher than that of deionized water).n alternating voltage is used in order to avoid electrolysis. The resistance is measured by a conductivity meter. Typical frequencies used are in the range 1â3 kHz. The dependence on the frequency is usually small, but may become appreciable at very high frequencies, an effect known as the DebyeâFalkenhagen effect.
From wire and cable literature, you can find that a 37-strand, Class B, 350kcmil bare conductor has a nominal O.D. of 0.681 inches. So, the insulation thickness is the quantity 1.34 inches minus 0.681 inches divided by 2, or 0.33 inches (330 mils). Per the reactance tables, the reactance value is 0.0373. Because the conductors are in a magnetic conduit, you must multiply this value by 1.50 (increase of 50%). Therefore, the inductive reactance-to-neutral at 6-Hz in ohms per 100 feet (XL) is equal to 0.0373 times 1.50, or 0.0560.
