Technically, mechanical engineering is the application of the principles and problem-solving techniques of engineering from design to manufacturing to the marketplace for any object. Mechanical engineers analyze their work using the principles of motion, energy, and force—ensuring that designs function safely, efficiently, and reliably, all at a competitive cost.
Mechanical engineers make a difference. That's because mechanical engineering careers center on creating technologies to meet human needs. Virtually every product or service in modern life has probably been touched in some way by a mechanical engineer to help humankind.
This includes solving today's problems and creating future solutions in health care, energy, transportation, world hunger, space exploration, climate change, and more.Being ingrained in many challenges and innovations across many fields means a mechanical engineering education is versatile. To meet this broad demand, mechanical engineers may design a component, a machine, a system, or a process. This ranges from the macro to the micro, from the largest systems like cars and satellites to the smallest components like sensors and switches. Anything that needs to be manufactured—indeed, anything with moving parts—needs the expertise of a mechanical engineer.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
2. Solar Collectors
•Solar collector is a device for collecting
solar radiation and transfer the energy to a
fluid passing in contact with it.
•The solar collectors, with its associated
absorber, is the essential component of any
system for the conversion of solar radiation
energy into usable form. E.g. heat and
electricity.
3. • The fundamental process now in general
use for HEAT conversion is the Green
House Effect
5. Non-concentration
[flat-plate collector]
• Heat produce at temperature below 90*C.
• Flat plate can be collect and absorb both
DIRECT and DIFFUSE solar radiation.
• They are effected by cloud and other
particles which are present in the
atmosphere
7. Liquid collector
• Liquid heating collectors are used for
heating water and non-freezing aqueous
solution and occasionally for non-aqueous
heat transfer fluids
9. • Typically a metal plate, usually of copper, steel
or aluminium material with tubing of copper in
thermal contact with the plates, are most
commonly used material.
• The absorber plate is usually made from metal
sheet 1 to2mm in thickness.
• Tubes which are also made from metals.
10. Tubes :
• Diameter :- 1.0 to 1.5
• They are soldered or clamped or bind to
bottom of absorber plate from 5 to 15cm.
• In some other type of design of liquid
collector we can found, the arrangement
of tubes are attached to the absorber
plate.
• Various type of arrangement are found
11. • The glass cover act as a convection shield
to reduce the losses from the absorber
plate beneath.
• Glass generally use for transparency.
12.
13. • Reflection may be reduced by coating with thin
films of certain substances. e.g. magnesium
fluoride
• We can use coating for increase HEAT
resistance.
HEAT TRANSFER SYSTEM:-
The heat generated in the absorber is removed by
continuous flow of a heat-transport medium,
either water or air.
diagram:
14. Problems:
1. A problem with this design is that in cold
weather, moisture may condense on the
inside of the transparent cover plate and
thus decrease the transmission of the
solar radiation.
2. A second problem is the corrosion of the
metal tube by the water.
15. Typical Air Collector
[solar air heater]
• Transparent cover
• Insulation
• Fluid tubes
• Absorbing surface
• Air has been used so far to a lesser extent as the heat transport
medium in solar collector.
• Zig-Zag flow path in Air collecter
17. Application
• heating building
• Drying agricultural produce and lumber
• Heating green house
• Air condition
• Air heater is useful for energy source for
heat engine
18. Adwantage
1. They have the advantage of using both
beam and diffuse solar radiation.
2. They do not require orientation toward
the sun.
3. They required little maintenance.
4. They are mechanically simpler than the
concentration reflector, absorbing
surfaces and orientation devices of
focusing collectors.
24. • The dimension of parabolic cylindrical collector
can be very over a wide range the length of a
reflecting unit may be roughly 3-5m and the
width about 1.5-2.4m,ten or more. Such unit are
often connected end to end in a row , such rows
are connected in parallel.
• Sun must in a particular direction.
• Generally oriented in the east –west or north-
south directions.
• East-west:-the collectors are laid flat on the
ground.
• North-south:-the can rays north to south
arranged like flat-plate collectors they are less
efficient.
25.
26. 2.Mirror-strip reflectors
• We use concave mirror strips
• The angle of mirror strips are different as
individuals
• Diagram:
27. 3.Fresnel lens collector
• In it use focusing effect of a Fresnel lens.
• Lens is rectangle, about 4.7-.95m in width.
• Solar radiation collect by this is 30%
greater than east-west collector.
• Diagram:
29. Advantage
• Surface required less material or provide
high collection of radiation.
• Heat loss rate is less than flat-plate
collection low maintenance .
• Can be used for power generation.
• We can get high concentration or radiation.
31. Disadvantage
• Only beam radiation collected.
• If sun direction is not correct then only
some mirrors are used others are not in
use.
• Additional optical losses such as
reflectance loss.
• High initial cost.
