Answer:
The minimum particle diameter that is removed at 85% is 1.474 * 10 ^⁻4 meters.
Solution
Given:
Length = 48 m
Width = 12 m
Depth = 3m
Flow rate = 4 m 3 /s
Water density = 10 3 kg/m 3
Dynamic viscosity = 1.30710 -3 N.sec/m
Now,
At the minimum particular diameter it is stated as follows:
The Reynolds number= 0.1
Thus,
0.1 =ρVTD/μ
VT = Dp² ( ρp- ρ) g/ 10μ²
Where
gn = The case/issue of sedimentation
VT = Terminal velocity
So,
0.1 = Dp³ ( ρp- ρ) g/ 10μ²
This becomes,
0.1 = 1000 * dp³ (1100-1000) g 0.1/ 10 *(1.307 * 10 ^⁻3)²
= 3.074 * 10 ^⁻6 = dp³ (.g01 * 10^6)
dp³=3.1343 * 10 ^⁻12
Dp minimum= 1.474 * 10 ^⁻4 meters.

Answer:
20 years
Explanation:
You do 2,000,000 ÷ 100,000 but you can simplify that to 20 ÷ 1 = 20
During those 20 years, the profits you earn will be 80,000 since when you do 2,000,000 x 0.04 but you can simplify that to 20,000 x 4 getting 80,000 and that quite doesn't reach 100,000 dollars
Answer:
1). Linear and syndiotactic poly(vinyl chloride); linear and isotactic polystyrene
2). Network phenol-formaldehyde; linear and heavily crosslinked cis-isoprene
3). Linear polyethylene, lightly branched isotactic polypropylene
Explanation:
1). It is very much possible to decide for the two polymers. Here the linear as well as the syndiotactic poly(vinyl chloride) are likely to be crystallize; the side - group phenyl of the polystyrene is more bulkier than CI side group for the poly(vinyl chloride). The syndiotactic as well as the isotactic isomers are likely to crystallize equally.
2). No we cannot decide for the two polymers. Both of them are crosslinked and the network polymers may not crystallize.
3). It is a possible to decide the two polymers. The linear polyethylene is likely to crystallize.
