A simplified mathematical model for an ion-exchange membrane attached to a gas-fed porous electrode is developed to simulate the oxygen electrode of a solid-polymer-electrolyte fuel cell. In particular, the present model is derived from an earlier ri

Summary This article considers the composition of juries, asking whether this is representative of the general populations from which the juries were drawn. The binomial and hypergeometric distributions are used for probability calculations. Several

Data were compiled and linearly correlated on the growth in the gross domestic product (GDP) with the academic chemical engineering literature over a recent 26-year period for five different English-speaking countries, namely, the United States, Cana

In this article, the dynamic equations describing the behaviour of the liquid level in a gasoline tank, as typically found on a conventional passenger car, are developed for a variety of geometric tank shapes. Generalized solutions to these equations

The problem of unsteady-state liquid flow across overflow devices of various shapes has been investigated. Dimensionless efflux times to evacuate a given amount of liquid from an upstream vessel or basin through an overflow conduit or weir as a funct

The kinetics of an autocatalytic termolecular reaction with overall stoichiometry of A + B → C + D was investigated. It is assumed that each of the three components A, B and C dissociate into reactive intermediate species, with equilibrium always e

Rigorous mathematical modeling of the process dynamics associated with the construction and filling of density gradient columns is presented in this article. These models incorporate the hydrostatic driving forces for fluid flow, friction losses asso

Steady‐state flow across parabolic and elliptical weirs is addressed. This situation may arise in the cases of actual flow through such cross‐sections, as in an overflow pipe in the side of a vessel, through saturator troughs as employed in the t

The time required to drain process or storage vessels of their liquid contents can be of crucial importance in many emergency situations. Over the years, many formulas have been developed to compute the time requirements for draining vessels of vario

The dynamic material balance equations for fluid drainage or leakage from process vessels of catenary shape through an opening at an arbitrary elevation were solved numerically and the results summarized in graphical form. Cases of both complete and
