Afine aqueous suspension containing 1 lbm of solids per cubic foot of suspension is to be filtered in a constant pressure filter. it is desired to filter at an average rate of 100 gpm, and the filter cake must be removed when it gets 2 in. thick. what filter area is required? data: -ap = 10 psi, p (wet cake) = 85 lbm/ft", k (permeability)=0.118 darcy

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
