Among the first instruments plastics molders, extruders, and compounders are likely to consider when outfitting a new lab is a melt-flow indexer or “melt indexer.” Known as an extrusion plastometer in ...

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

This article describes how a multivariable pressure transmitter with built-in dynamic compensation can correct for many of the errors and inaccuracies that can occur in differential pressure based ...

Compressor speed as a function of molecular weight, while maintaining the same suction and discharge pressure and mass flow rate. Polytropic head and efficiencies as a function of gas molecular weight ...

When thinking mathematically, most people think in proportions. For example, if someone is baking cookies and they want to make a double batch, they intuitively know they need to double the amount of ...
