Shaker speed unit to Ethereum

1. The separation factor fr of the centrifuge is proportional to the square of the rotational speed n of the centrifuge. The formula is as follows:
fr = R ω 2/g
ω= two π N / 60

depends on the radius (maximum outer diameter) of the centrifuge. After knowing the radius r, you can convert 3000rpm to 314rad / s, and then 314 * 314 * r / g

2. Are you wrong? It's not D. it should be R /, a bit like D. 50R / min is 50 revolutions per minute.

4. It should be said that the faster the shaking speed is, the faster the dissolved oxygen dissolves. However, there is an upper limit for the concentration of dissolved oxygen in water. No matter how fast the shaking speed is, the dissolved oxygen will not increase. As for the conversion formula, the dissolved oxygen dissolving speed is not only related to the shaking speed, but also related to the water temperature, the saturation degree of dissolved oxygen, water volume and other factors. There is no unified formula

5. Three in a second

6. Syphilis infection should be treated in time. I have used gonorrhea before; Meichen 92; Shu and Chen 92; Turn to 92; Yin and Chen 92; Set of 92; I've never had a relapse
