Explanation:
The volumetric flow rate of water will be as follows.
q = 
= 0.0378 
Diameter =
= 0.2032 m
Relation between area and diameter is as follows.
A =
=
= 0.785 x 0.2032 x 0.2032
= 0.0324
Also, q = A × V
or, V = 
= 
= 1.166 m/s
As, viscosity of water = 1 cP =
Pa-s
Density of water = 1000
Therefore, we will calculate Reynolds number as follows.
Reynolds number =
=
= 236931.2
Hence, the flow will be turbulent in nature.
Thus, we can conclude that the Reynolds number is 236931.2 and flow is turbulent.
Williamson synthesis is the most common way for obtaining ethers, called after its developer Alexander Williamson. It is an organic reaction of forming ethers from an organohalide and an alkoxide. The reaction is carried out according to the SN2 mechanism.
On the attached picture it is shown required alkoxide ion, <span>alkyl(aryl)bromide and the ether that forms from the reactants. </span>
