Surface Tension vs Interfacial Tension. Both surface tension and interfacial tension are effects based on liquids. Both these effects take place due to the unbalanced intermolecular forces between the liquid or solutions molecules.
Statistical process control (SPC) is a method of quality control which employs statistical methods to monitor and control a process. This helps ensure the process operates efficiently, producing more specification-conforming product with less waste (rework or scrap).
A stable process is one that is consistent over time with respect to the center and the. spread of the data. Control Charts help you monitor the behavior of your process to. determine whether it is stable. Like Run Charts, they display data in the time. sequence in which they occurred. However, Control Charts are more efficient. that Run Charts in assessing and achieving process stability. Your team will benefit from using a Control Chart when you want to (Viewgraph 2) Monitor process variation over time. Differentiate between special cause and common cause variation. Assess the effectiveness of changes to improve a process. Communicate how a process performed during a specific period.
