A cylindrical steel tank is coated with a thick layer of zinc on the inside. The tank is 34 cm in diameter, 61 cm high and filled to the 27 cm level with aerated water. If the corrosion current is 5.9x10-5 A/cm2, how much zinc in grams per day is being corrode
PLEASE DOUBLE CHECK THE ANSWER THIS IS MY FINAL ATTEMPT< THANKS A LOT
Solutions
Expert Solution
Given information in the problem:
Diameter of tank (DT) = 34 cm
Height of tank (HT) = 61 cm
Filled height of tank with aerated water (HF) = 27 cm
Corrosion current density,
---------------------------------------------------------------------------------------------------------------------
Tank surface area in contact with aerated water (AT) = Bottom surface area + Curved surface area with filled tank height
---------------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------------
Corrosion rate,
W = Total amount of Zinc corrode (gram)
t = the total time of corrosion (s)
I = Corrosion current (A)
M = Molecular weight (gram/mole)
n = Oxidation number for Zinc
F = Faraday constant (A.s/mole)
---------------------------------------------------------------------------------------------------------------------
So, 6.5464 gram Zinc being corrodes per day.

A tank holds a 1.44-m thick layer of oil that floats on a 0.96-m
thick layer of brine. Both liquids are clear and do not intermix.
Point O is at the bottom of the tank, on a vertical axis.
The indices of refraction of the oil and the brine are 1.40 and
1.52, respectively. A ray originating at O crosses the
brine-oil interface at a point 0.5 m from the axis. The ray
continues and emerges into the air above...

(a)
At a reclamation site, a 6-m thick sand layer overlies a 5.8-m
thick clay layer, which is underlain by impermeable rock stratum.
The water level is initially 2.5 m above the ground surface. The
saturated unit weights of sand and clay are 19 kN/m3 and 17 kN/m3,
respectively. A 5-m thick layer of fill will be placed on the
original ground surface, and the unit weights of fill are 19 kN/m3
and 20 kN/m3 above and below water table,...

A layer of cork 6 inch thick is used as layer of
thermal insulation in a flat wall. The temperature of the cold side
is 40 oF and that of the warm side is 180 oF. The thermal
conductivity of the cork at 32 oF is 0.021 Btu/ft-h-oF and that at
200 oF is 0.032. The area of the wall is 25 ft. Estimate the rate
of heat transfer through the wall. Answer: 182 Btu/hr

Modern pennies are composed of zinc coated with copper. A
student determines the mass of a penny to be 2.480 g and then makes
several scratches in the copper coating (to expose the underlying
zinc). The student puts the scratched penny in hydrochloric acid,
where the following reaction occurs between the zinc and the HCl
(the copper remains undissolved):
Zn(s)+2HCl(aq)→H2(g)+ZnCl2(aq)
The student collects the hydrogen produced over water at 25 ∘C. The
collected gas occupies a volume of 0.903 L...

A 20 m thick saturated clay layer is normally consolidated. At
mid-depth in this layer, the void ratio (e) is 1.110, the
coefficient of compressibility (av) is 5.74 x103 cm2=N.
Recall that w = 9.81 kN/m3. a) Assuming that a 122 cm lowering of
the ground water table (GWT) occurs in the soil overlying the clay
layer, what settlement will occur in the soil overlying the clay
layer because of the ultimate primary consolidation of the clay
layer? Express your...
