Sep 06, 2015· Sub ohm vaping involves the use of a coil that has a resistance of less than an ohm. Just a few years ago, the lowest resistance you could find for standard cartomizers and clearomizers was 1.2 ohms. Back then, vaping below one ohm (or "sub-ohming") was the province of advanced Vapers who wanted more power from their fixed-voltage devices.
Mill motor, 2.9MW, 6.3KV, rotor current: 775A, rotor voltage: 2770V In this case sometimes we recorded 775A as starting current and in other times we recorded 400 A for rotor current during start and for stator the current is variable, in some case it was 85 A, and in other was larger than 400a. This motor starts with liquid starter.

Apr 22, 2019· Equivalent liquid resistance (1/R) = (1/R 1) + (1/R 2) Stoke's Law. When a small spherical body falls in a long liquid column, then after sometime it falls with a constant velocity, called terminal velocity. When a small spherical body falls in a liquid column with terminal velocity then viscous force acting on it is. F = 6πηrv
The mill used for this comparison is a 4.4-meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 s.ton per hour.
