It depends on how much the cans of food cost
Answer:
a) 513775.5 m^3 ≈ 51.38 * 10^4 m^3
b) 256887.75 m^3 ≈ 25.69 * 10^4 m^3
Step-by-step explanation:
Given data :
Depth of pond = 2m
flow in the stream = 20 cfs = 4.8931 * 10^4 m^3/day
settling rate = 0.2 m/day
rate constant ( k )= 0.2 / 2 = 0.1 / day
steady-state removal of the solids required = 65%
<u>A) determine size of a single CSTR to achieve 65%</u>
First determine the time required to achieve this using the relation below
C =
∴ t =
= ( -1 / 0.1 ) * (- 1.05 ) = 10.5 day
The size of a single CSTR required = ( 4.8931*10^4 ) * (10.5 ) = 513775.5 m^3
<u>B) determine the sizes of a pair of identical CSTRs in series needed to achieve the desired removal</u>
sizes of a pair = 513775.5 / 2 = 256887.75 m^3
Answer: x > 4
x > 4 would look like that on the graph. If it was x is greater than or equal to 4, then the circle would be completely filled in. Hope this helped!
Answer:
1320x^2y−4224x^2−3165xy+10128x+375y−1200
Step-by-step explanation:
(8x−1)(11x−25)(15y−48)
=((8x−1)(11x−25))(15y+−48)
=((8x−1)(11x−25))(15y)+((8x−1)(11x−25))(−48)
=1320x2y−3165xy+375y−4224x2+10128x−1200
=1320x^2y−4224x^2−3165xy+10128x+375y−1200
