Answer:
BOD concentration at the outflow = 17.83 mg/L
Explanation:
given data
flow rate of Q = 4,000 m³/day
BOD1 concentration of Cin = 25 mg/L
volume of the pond = 20,000 m³
first-order rate constant equal = 0.25/day
to find out
What is the BOD concentration at the outflow of the pond
solution
first we find the detention time that is
detention time t =
detention time t =
detention time = 5 days
so
BOD concentration at the outflow of pond is express as
BOD concentration at the outflow =
here k is first-order rate constant and t is detention time and Cin is BOD1 concentration
so
BOD concentration at the outflow =
BOD concentration at the outflow = 17.83 mg/L
Answer:
The time required to elute the two species is 53.3727 min
Explanation:
Given data:
tA = retention time of A=16.63 min
tB=retention time of B=17.63 min
WA=peak of A=1.11 min
WB=peak of B=1.21 min
The mathematical expression for the resolution is:
The mathematical expression for the time to elute the two species is:
Here
ReB = 1.5
