You have designed a treatment system for contaminant z. the treatment system consists of a pipe that feeds into a cstr. the pipe has a volume of 15 m3 and the cstr has a volume of 60 m3 . the inflow is 10 m3 /d and the influent z concentration is 2,500 mg/l. if the effluent from the cstr has a z concentration of 500 mg/l, what is the degradation

0.667 per day.

Explanation:

Our values here are

Degradation constant=k and is unknown.

We calculate the concentration through the formula,

Replacing values we have

That is the degradation constant of Z-contaminant

it was a fall down when it happens

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
