Chemical Potential of Nitrogen at High Pressure and High Temperature: Application to Nitrogen and Nitrogen-Rich Phase Diagram Calculations. At the top of the mercury column in the tube (point 3 in the sketch), the pressure is nearly a total vacuum. The identifying of the pump can be done with the design as well as positions. API 510 provides guidelines for pressure vessel inspection. Chem. These pressure transducers are used in high-pressure measuring applications. The application mainly includes the type of fluid you desire to pump, the distance you desire to move the fluid, and the quantity you require to get over a particular time frame. In sterilization by using an autoclave, saturated steam under pressure spreads into cavities of material to help effective microbial kill.
