1.Introduction – Installing an Orifice Meter

At the end of this post you will find the EMERSON document who explains the basic orifice plate installation guidelines, including:

This post is mainly a set of rules for the orifice plate installation like an orifice flow meter installation guidelines. In order that a flow instrument may accurately read flow, it’s necessary that the installation comply with certain rules.

Answer 2

Answer:

Explanation:

Let the relative abundance % of Ne−20=x1

So, ​relative abundance % of Ne−22=x2

Now we know that atomic mass = sum of relative abundance in atomic mass of each isotope / 100%            

20.2=20 x1 +  20 x2 / x1 + x2                          

​  

x1/x2=9/ 1    

take some constant solve ahead

            Relative abundance

 x 1   %=9/10      ×100=90% lighter isotopes      

  x2    %= 1/10     ×100=10% = heavier isotope
