A series of experiments was conducted in a batch reactor to test the disinfection by chlorine of E. coli. In each experimental run, the concen tration of free available chlorine was varied and the time required to kill 99% of the organisms was determined. The results showed that a CT value of 200 min mg/L was sufficient to achieve a 2-log removal.
(a) In Chick's law, what value of k corresponds to a chlorine concentration of 1 mg/L?
(b) Specify the hydraulic retention time for a PFR designed to achieve 99.9% removal of E. coli. with a chlorine concentration of 1 mg/L.
(c) Specify the hydraulic retention time for a CMFR designed to achieve 99.9% removal of E. coli. with a chlorine con centration of 1 mg/L
Calculate the resistance coefficient K for a ball-type check valve placed in a 2-in schedule 40 steel pipe carrying 650 gal/min of oil (sg = 0.90)
Determine the magnitude and direction of the force P in so that the resultant of P and the 900N force is a vertical force of 2700N directed downward using.
