Chezy and Manning developed equations that are used to determine the average volumetric flowrate in open channels. This article explains a laboratory method that was developed and tested to further ...

What is a peak expiratory flow rate test? The peak expiratory flow rate (PEFR) test measures how fast a person can exhale. The PEFR test is also called peak flow. This test is commonly performed at ...

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 ...

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 ...
