ppm is about the length of the unit Mody? And ocean drilling related to
Category:oil and gas
Question:
ppm in addition to the concentration outside the unit, or the length of the unit Mody? Can *** ppm with a diameter that? Especially in the offshore drilling inside, saying that prior to drilling debris generated by the sea would probably be ranked lower than 15ppm. . . . Or I am wrong unit? Thank you ~ ~ ~
Answer:
PPM is a ratio unit is defined as the number per million contained in certain types of content, both for the concentration can also be used for other aspects.
For example:
a product non-performing rate of 30PPM, refers to the product per 1 million the number of non-performing products to 30
Chinese:ppm是有关长度的单位么？与海洋钻井有关
类别: 石油天然气
问题:
ppm除了是浓度单位外，还是有关长度的单位么？可不可以用直径为***ppm表示？尤其是在海洋钻井里面，说以前钻井产生的岩屑小于15ppm可以排海。。。。或者我记错了单位？谢谢~~~
回答:
PPM是一种比率单位,是指每百万数量中所含某类的含量, 既可用于浓度, 也可用于其它方面.
例如:
某产品不良率为 30PPM, 指的是每1000000个产品中不良品的数量为30个
