  2. Centrifuge - Wikipedia

    en.wikipedia.org/wiki/Centrifuge

    Many designs have been shared for free and open-source centrifuges that can be digitally manufactured. The open-source hardware designs for hand-powered centrifuge for larger volumes of fluids with a radial velocity of over 1750 rpm and over 50 N of relative centrifugal force can be completely 3-D printed for about $25.

  3. Centrifugation - Wikipedia

    en.wikipedia.org/wiki/Centrifugation

    For instance, the RCF of 1000 x g means that the centrifugal force is 1000 times stronger than the Earth's gravitational force. RCF is dependent on the speed of rotation in rpm and the distance of the particles from the center of rotation. The most common formula used for calculating RCF is: [7]

  4. Revolutions per minute - Wikipedia

    en.wikipedia.org/wiki/Revolutions_per_minute

    Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or r⋅min −1) is a unit of rotational speed (or rotational frequency) for rotating machines. One revolution per minute is equivalent to ⁠ 1 / 60 ⁠ hertz .

  5. Rotational frequency - Wikipedia

    en.wikipedia.org/wiki/Rotational_frequency

    Its angular frequency is 360 degrees per second (360°/s), or 2π radians per second (2π rad/s), while the rotational frequency is 60 rpm. Rotational frequency is not to be confused with tangential speed, despite some relation between the two concepts. Imagine a merry-go-round with a constant rate of rotation.

  6. Specific speed - Wikipedia

    en.wikipedia.org/wiki/Specific_speed

    Given a flow and head for a specific hydro site, and the RPM requirement of the generator, calculate the specific speed. The result is the main criteria for turbine selection or the starting point for analytical design of a new turbine. Once the desired specific speed is known, basic dimensions of the turbine parts can be easily calculated.

    A standard ultracentrifuge by manufacturer Beckman Coulter. An ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1 000 000 g (approx. 9 800 km/s²). [1]

    Toby Fischer lives in South Dakota, where just 27 doctors are certified to prescribe buprenorphine -- a medication that blunts the symptoms of withdrawal from heroin and opioid painkillers. A Huffington Post analysis of government data found nearly half of all counties in America don't have such a certified physician. So every month, Fischer and his mother drive to Colorado to pick up their ...
