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 ...

The mathematics for properly designing ventilation and emission control systems have been around for quite awhile, but our studies of hundreds of systems show that many are wasting energy, while still ...

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 ...

“We develop a generalized three-phase Newton power flow algorithm for modern shipboard microgrids incorporating inverter-based resources. The proposed method enables to solve shipboard power flow when ...

A large-scale power grid’s ability to transfer energy from producers to consumers is constrained by both the network structure and the nonlinear physics of power flow. Violations of these constraints ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...
