The document discusses the layered internal structure of the Earth based on differences in composition, density, seismic wave velocities, and mechanical properties. It is divided into five main layers from outermost to innermost: the crust, mantle, outer core, and inner core. The crust and upper mantle are solid and composed of silicate rocks, while the lower mantle, outer core, and inner core are increasingly dense with the inner core being solid iron-nickel alloy. Seismic discontinuities exist that help delineate the boundaries between layers.

Lesson 8: Shape,Size and Structure of the earthJamaica Olazo
The Earth was formed at the same time as the other planets of the Solar System from a vast spinning disc of gas and dust.
Scientists have gathered valuable information about the Earth with the use of advance science and technology to help us understand our planet.
They have determined the size and shape of the Earth by using precise instruments and equipment.
The Earth is shaped like an Orange because it bulges at the Equator and is flat at the polar regions.
Therefore, the Earth is an Oblate Spheroid.
Geodesy – the science that studies and measures the exact size and dimensions of the Earth.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. The study of the passage of
seismic (earth quack)
waves through the earth
have helped greatly in
knowing the interior of the
earth.
The interior structure of
the Earth is layered in
spherical shells, like
an onion. Earth has an
outer silicate solid crust, a
highly viscous mantle, a
liquid outer core that is
much less viscous than the
mantle, and a solid inner
core.
EARTH STRUCTURE 2
3. The structure of Earth can
be defined in two ways: by
mechanical properties such
as rheology ( the study of
the flow of matter, primarily
in the liquid state) , or
chemically.
Mechanically, it can be
divided
into lithosphere, asthenosp
here, mesospheric
mantle, outer core, and
the inner core.
The interior of Earth is
divided into 5 important
layers. Chemically, Earth can
be divided into the crust,
upper mantle, lower mantle,
outer core, and inner core.
EARTH STRUCTURE 3
4. At depth of 30 to 40 km, the velocity
of both P and S waves increase
abruptly. The velocity of p waves
increases from about 6.5 km per
second to about 8 km per second.
This discontinuity surface is called
the “mohorvicic discontinuity”.
Ta depth of 2900 km, from the
Mohorvicic discontinuity to a depth
of 2900 km, the velocity of both P
and S wave increases gradually. But
at 2900 km the P waves are sharply
reflected and refracted, and their
velocity drops abruptly from about
13 km per second to about 8 km per
second.
The S waves are lost entirely. This
discontinuity surface separates the
“mantle” of the earth from the “core”.
At depth of 5000 km below the
earth’s surface, there is an abrupt
increase in the velocity of P waves.
This discontinuity surface suggests
the existence of an “inner core”.
EARTH STRUCTURE 4
5. The core is situated from 2900 km depth up the
centre of the earth (6370 km ).
Since the S waves do not pass through the
core. Seismic measurements show that the core is
divided into two parts, a "solid" inner core with
a radius of ~1,220 km and a liquid outer
core extending beyond it to a radius of ~3,400 km.
The densities are between 9,900 and
12,200 kg/m3 in the outer core and 12,600–
13,000 kg/m3 in the inner core. The inner core was
discovered in 1936 by Inge Lehmann and is generally
believed to be composed primarily of iron and some
nickel.
EARTH STRUCTURE 5
6. The inner core is believed to consist primarily of a nickel-iron
alloy known as NiFe: 'Ni' for nickel, and 'Fe' for ferrum
or iron. Because the inner core is denser (12.8 ~ 13.1)g⁄cm³ than
pure iron or nickel, even under heavy pressures.
Earth's outer core is a liquid layer about 2,266 km (1,408 mi)
thick composed of iron and nickel that lies above Earth's
solid inner core and below its mantle. Its outer boundary lies
2,890 km (1,800 mi) beneath Earth's surface. The transition
between the inner core and outer core is located approximately
5,150 km (3,200 mi) beneath Earth's surface.
The temperature of the outer core ranges from 4400 °C (8000 °F)
in the outer regions to 6100 °C (11000 °F) near the inner core.
Because of its high temperature, modeling work has shown that
the outer core is a low viscosity fluid (about ten times the
viscosity of liquid metals at the surface) that
convects turbulently.
EARTH STRUCTURE 6
7. The mantle lies beneath the earth’s crust and
it extends to a depth of 2,890 km, making it the
thickest layer of Earth. The pressure at the bottom of
the mantle is ~140 GPa (1.4 Matm). The mantle is
composed of silicate rocks that are rich in iron and
magnesium relative to the overlying crust. Although
solid, the high temperatures within the mantle cause
the silicate material to be sufficiently ductile that it
can flow on very long timescales. It has been divided
into the upper mantle and lower mantle. The upper
mantle lies between 35 km and 1000 km depth, and
is made up of ultra basic rocks like peridotite ( sp. Gr.
3.3) the lower mantle is between 1000 km and 2890
km, and contains pallasite (sp. Gr. 5.7) which is a
mixture of basic rocks and metallic iron.
EARTH STRUCTURE 7
8. The outer most layer of solid rock,
which lies above the Mohorovicic
discontinuity and has an average
thickness of 35 km, is known as
the crust of the earth. Under the
continents it is possible to
distinguish two layers in the earth
crust. The upper layer which is less
dense (sp. Gr. 2.65) and granitic in
character is known as the “sial” ;
while the lower layer which is
basaltic in character (sp. Gr. 3.0) is
known as “sima”. The term sial
represents rock rich in silica and
alumina, and term sima represents
rock containing silica and
magnesia. Under oceans only sima
layer is found and the sial layer
appears to be absent.
