Assume that a chemical reaction involving the removal of a given contaminant follows first order kinetics. The rate constant, k, is 0.5 hr-1. Compare the performance of the following reactors/reactor combinations. Provide your comments your results. Note: ? is the residence (retention) time. (CMFR = completely mixed flow reactor; PFR = plug flow reactor
(a) a single CMFR, ? = 2 hrs
(b) a single PFR, ? = 2 hrs
(c) two CMFRs in series, each ? = 1 hr
(d) a CMFR followed by a PFR, each ? = 1 hr (e) a PFR followed by a CMFR, each ? = 1 hr
A steel circular hollow cylinder is supported on a circular steel plate.This arrangement is supported on a concrete pedestal. The column has outside diameter d = 250 mm and supports a axial load P = 750 kN.
estimate the mass and volume of sludge produced from unreated wastewater without and with the use of ferric chloride for the enhanced removal of TSS. Also, estimate the amount of lime required for the specified ferric schloride dose.
A concrete cylinder having a diameter of 6 in and a gauge length of 12 in is tested in compression the results of the test are reported in the table as load vs contraction
If a unit mass of groundwater accelerates from rest to an average linear velocity of 1 m per year and climbs a vertical distance of 1 m, compare the ratio of kinetic energy to the potential energy of the unit of groundwater.
A cylindrical chimney,1 m in diameter and 2.5 m tall is exosed to a uniform 50km/hr wind at standard atmospheric conditions.End effects and gusts may be neglected.Estimate the bending moment at the base of the chimneydue to wind force?
Assuming that the coefficient of static friction µs is the same at A and B, determine the smallest value of µs for which equilibrium is maintained. The weight force acts at the center of the length of the ladder.
The lubbock board of city development has decided to ask the city council to construct a tunnel under the snowcapped mountain range east to downtown lubbock so that out of town visitors can reach historic prairie dog town without becoming lost and en..
