Answer:
The extraction is done by electrolysis. The ions in the aluminum oxide must be free to move so that electricity can pass through it. Aluminum oxide has a very high melting point (over 2000°C) so it would be expensive to melt it. Aluminum oxide does not dissolve in water, but it does dissolve in molten cryolite.

Answer:
The couch will not move because the people are not working together. Maybe if they call someone to help they can make some progress.
Answer:
Explanation:
The process of gaining or losing electrons from a neutral atom or molecule is called ionization. Atoms can be ionized by bombardment with radiation, but the more purely chemical process of ionization is the transfer of electrons between atoms or molecules
Explanation:
The given data is as follows.
Diameter = 0.1 m, = 1000 kPa
= 500 kPa
Change in pressure = 1000 kPa - 500 kPa = 500 kPa
Since, 1000 Pa = 1 kPa. So, 500 kPa will be equal to .
Q = 5 = = 0.0833
It is known that Q =
where, A = cross sectional area
V = speed of the fluid in that section
Hence, calculate V as follows.
V =
=
=
= 10.61 m/sec
Also it is known that Reynold's number is as follows.
Re =
=
= 1061032.954
As, it is given that the flow is turbulent so we cannot use the Hagen-Poiseuille equation as follows. Therefore, by using Blasius equation for turbulent flow as follows.
L =
= 90.328 m
Thus, we can conclude that 90.328 m length galvanized iron line should be used to reach the desired outlet pressure.
