In the first step, select the pressure in the rightmost picture (which is the current pressure), in the second step, select the original boiling point of the material in the middle picture, and in the third step, use a ruler to connect them and extend them to the scale of the first picture, and you can read the boiling point under the current pressure. It is used to see at what temperature and under what vacuum the material can be extracted.
Find the corresponding data according to the straight line
I think two points and a line, as long as you know the two parameters, connect the straight line to find the third data.
study* Now that the system pressure and the normal pressure boiling point of the material are known, calculate the boiling point under the system pressure. See how much temperature and how much vacuum can pull out the material.
