Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

This is the second of eight articles from our Nozzle Knowledge Series. Prefer to watch a video, click here. Flow rate, the volume of water passing through a nozzle, per unit of time, is clearly an ...

The many applications of flow measurement include uses in water supply, medical research, oil exploration, food processing and distribution of gas. The uses of this technology are very diverse, with ...

IRR measures the rate needed to break even on an investment. Calculate IRR by setting NPV to zero and solving for the discount rate. Use Excel's IRR function by inputting initial cost and cash inflow.

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 ...
