The quantity of electricity
Solution
According to Faraday, the amount of current flowing in the electrolysis cell is closely related to the amount of substance that reacts
1 Faraday is the amount of electricity that is passed in the electrolysis cell to obtain 1 mole of electrons. 1 mole of electrons is equivalent to an electric charge of 96500 Coulombs.
The conversion / relationship can be stated as follows:
1 Faraday = 1 mole of electrons = 96500 Coulombs
1 faraday = coulomb / 96500
Can be formulated
Coulomb = Q = I. t so:
so for 2 moles electrons :
= 2 x 96500 C
= 193000 C
= 2 Faraday
Explanation:
The given data is as follows.
= 85 psig,
=
= 15 psia
Q = 1620 gpm, d = 2.5 inch, l = 8 ft = 2.4384 m
According to Darey-Weisbach equation,
......... (1)
Value of 'f' will be decided on the basis of Reynold number.
As, it is known that
where, =
kg/ms
As it is known that 1 gpm =
So, = 3.67 gpm
Therefore, Q =
=
= 0.1226
In, 1 inch = 2.54 cm = 0.0254 m
Therefore, d = 2.5 \times 0.0254 = 0.0635 m
V =
=
= 38.73 m/s
Hence, we will calculate Reynold number as follows.
=
= 2459355
As > 2000 then, it means that flow is turbulent.
As, f = 0.079
= 0.001994
Putting all the values into equation (1) formula as follows.
=
=
Thus, we can conclude that friction loss from the main to the discharge point is .
