Wind power harnesses the kinetic energy of wind to generate electricity. It works by converting the mechanical energy of wind turning the turbine blades into electrical energy via a generator. The amount of power generated depends on factors like wind speed, turbine size, and air density. Modern wind turbines can achieve efficiencies of around 60% of the theoretical maximum power available from the wind. While wind power has environmental benefits and the potential to meet a large portion of US energy needs, concerns include the visual and noise impacts of turbines as well as risks to bird populations. Proper planning aims to maximize energy generation while minimizing these effects.

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.

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.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

What is it?
How does it work?

U.S. Stats and
Examples
By: Roger Rivera
2. WIND POWERWIND POWER - What is it?- What is it?
All renewable energy (except tidal and geothermal power), ultimately
comes from the sun
The earth receives 1.74 x 1017
watts of power (per hour) from the sun
About one or 2 percent of this energy is converted to wind energy
(which is about 50-100 times more than the energy converted to
biomass by all plants on earth
Differential heating of the earth’s surface
and atmosphere induces vertical and horizontal
air currents that are affected by the earth’s
rotation and contours of the land WIND.
~ e.g.: Land Sea Breeze Cycle
3. • Winds are influenced by the ground surface at altitudes up to
100 meters.
• Wind is slowed by the surface roughness and obstacles.
• When dealing with wind energy, we are concerned with
surface winds.
• A wind turbine obtains its power input by converting the
force of the wind into a torque (turning force) acting on the
rotor blades.
• The amount of energy which the wind transfers to the rotor
depends on the density of the air, the rotor area, and the wind
speed.
• The kinetic energy of a moving body is proportional to its
mass (or weight). The kinetic energy in the wind thus depends
on the density of the air, i.e. its mass per unit of volume.
In other words, the "heavier" the air, the more energy is
received by the turbine.
•at 15° Celsius air weighs about 1.225 kg per cubic meter, but
the density decreases slightly with increasing humidity.
4. A typical 600 kW wind turbine has a rotor diameter of 43-44 meters,
i.e. a rotor area of some 1,500 square meters.
The rotor area determines how much energy a wind turbine is able to
harvest from the wind.
Since the rotor area increases with the square of the rotor diameter, a
turbine which is twice as large will receive 22
= 2 x 2 = four times as
much energy.
To be considered a good location for
wind energy, an area needs to have
average annual wind speeds of at least 12
miles per hour.
5. WINDMILL DESIGNWINDMILL DESIGN
A Windmill captures
wind energy and then
uses a generator to
convert it to electrical
energy.
The design of a
windmill is an integral
part of how efficient it
will be.
When designing a
windmill, one must
decide on the size of the
turbine, and the size of
the generator.
6. LARGE TURBINES:
• Able to deliver electricity at lower cost
than smaller turbines, because foundation
costs, planning costs, etc. are independent
of size.
• Well-suited for offshore wind plants.
• In areas where it is difficult to find sites,
one large turbine on a tall tower uses the
wind extremely efficiently.
7. SMALL TURBINES:
Local electrical grids may not be able to handle the large electrical
output from a large turbine, so smaller turbines may be more
suitable.
High costs for foundations for large turbines may not be
economical in some areas.
Landscape considerations
8. Wind Turbines: Number of Blades
Most common design is the three-bladed turbine. The most important reason is
the stability of the turbine. A rotor with an odd number of rotor blades (and at least
three blades) can be considered to be similar to a disc when calculating the dynamic
properties of the machine.
A rotor with an even number of blades will give stability problems for a machine
with a stiff structure. The reason is that at the very moment when the uppermost
blade bends backwards, because it gets the maximum power from the wind, the
lowermost blade passes into the wind shade in front of the tower.
9. • Wind power generators
convert wind energy
(mechanical energy) to
electrical energy.
• The generator is
attached at one end to the
wind turbine, which
provides the mechanical
energy.
• At the other end, the
generator is connected to
the electrical grid.
• The generator needs to
have a cooling system to
make sure there is no
overheating.
10. SMALL GENERATORS:
Require less force to turn than a larger ones, but give much lower
power output.
Less efficient
i.e.. If you fit a large wind turbine rotor with a small generator it
will be producing electricity during many hours of the year, but it
will capture only a small part of the energy content of the wind at
high wind speeds.
LARGE GENERATORS:
Very efficient at high wind speeds, but unable to turn at low wind
speeds.
i.e.. If the generator has larger coils, and/or a stronger internal
magnet, it will require more force (mechanical) to start in motion.
11. o A windmill built so that it too severely interrupts the airflow
through its cross section will reduce the effective wind velocity
at its location and divert much of the airflow around itself,
thus not extracting the maximum power from the wind.
o At the other extreme, a windmill that intercepts a small
fraction of the wind passing through its cross section will
reduce the wind’s velocity by only a small amount, thus
extracting only a small fraction of the power from the wind
traversing the windmill disk.
o Modern Windmills can attain an efficiency of about 60 % of
the theoretical maximum.
12. P/m^2 = 6.1 x 10^-4 v^3
*The power in wind is
proportional to the cubic wind
speed ( v^3 ).
WHY?
~ Kinetic energy of an air mass
is proportional to v^2
~ Amount of air mass moving
past a given point is proportional
to wind velocity (v)
13. * An extra meter of tower will cost roughly 1,500 USD.
14. A typical 600 kW turbine costs about $450,000.
Installation costs are typically $125,000.
Therefore, the total costs will be about $575,000.
The average price for large, modern wind farms is
around $1,000 per kilowatt electrical power installed.
Modern wind turbines are designed to work for some
120,000 hours of operation throughout their design
lifetime of 20 years. ( 13.7 years non-stop)
Maintenance costs are about 1.5-2.0 percent of the
original cost, per year.
15. The U.S. currently has more than 1,600 MW of installed
capacity and produces about 3 billion KWh of electricity
each year.
This is enough to meet the annual residential needs of 1
million people.
More than 90 percent of this power is produced by three
wind farms in California (Altamont Pass, Tehachapi and
Palm Springs).
16.
17.
18.
19. • The U.S. contains enough useable wind resource to produce
more electricity than the nation currently uses.
• The majority of this usable resource is in the Great Plains
region. North Dakota alone has enough suitable wind
resource to supply 36 percent of the electricity consumed in
the U.S.
• In addition, development of major global wind energy
markets could significantly impact jobs—recent studies show
that each billion kilowatt-hours of annual wind energy
generation creates between 440 to 460 jobs.
20. Advantages of Wind Power
• The wind blows day and night, which allows windmills to
produce electricity throughout the day. (Faster during the day)
• Energy output from a wind turbine will vary as the wind varies,
although the most rapid variations will to some extent be
compensated for by the inertia of the wind turbine rotor.
• Wind energy is a domestic, renewable source of energy that
generates no pollution and has little environmental impact. Up to
95 percent of land used for wind farms can also be used for other
profitable activities including ranching, farming and forestry.
• The decreasing cost of wind power and the growing interest in
renewable energy sources should ensure that wind power will
become a viable energy source in the United States and worldwide.
21. Wind Turbines and the Landscape
- Large turbines don’t turn as fast attract less attention
- City dwellers “dwell” on the attention attracted by windmills
Sound from Wind Turbines
- Increasing tip speed less sound
- The closest neighbor is usually 300 m experiences almost no noise
Birds often collide with high voltage overhead lines, masts, poles, and
windows of buildings. They are also killed by cars in traffic. However,
birds are seldom bothered by wind turbines.
The only known site with bird collision problems is located in the
Altamont Pass in California.
Danish Ministry of the Environment study revealed that power lines
are a much greater danger to birds than the wind turbines.
Some birds even nest on cages on Wind Towers.
