This aircraft has 440 seats in one of is two models and 400 seats in the other one.

7. Airbus A350-900

Airbus A350 is one of the new models by Airbus. A350-900 has capacity to accommodate 325 passengers in one model and 440 in the other one.

8. Airbus A340-500

This aircraft can carry 372 passengers and its other model has seats to carry 313 passengers.

9. Airbus A333-300

This airplane can carry 277 passengers and its other model can carry 440 passengers.

10. Airbus A340-300

The last on the list of largest airplanes by passenger capacity is A333-300.This aircraft can carry 267 passengers and its other model can carry 295.

As you can see that even the last one in the list of largest aircrafts by seating capacity can carry a huge number of passengers (295). Imaging how big the A380 is, which carries 853 passengers! It would definitely be a great experience boarding this plane and even the others that are mentioned in the list. Traveling in airplane, especially if it is huge, spacious is very joyful.

Are you a Civil Engineer? You may like to look at the top certifications for Civil Engineers, which are highly in demand by the employers:

FE (Fundamentals of Engineering)

The exam fee is US$ 225. This is a first step for anyone before he/she can go for EIT or PE certification. Exam registrations for FE, PE, EIT are done online at http://ncees.org/ and the exam is held at Pearson VUE testing centers worldwide.

PE (Professional Engineer)

Pass rate for Civil Engineers is about 70%.  Course fee in US is about $1400.   Exam fee is US$ 350

One needs to work under a Professional Engineer for 4 years, should be a graduate   and pass the FE (Fundamentals of Engineering) exam before he can become eligible for the PE exam.

EIT (Engineer in Training)

One needs to have passed FE (Fundamental of Engineering) exam, should be a graduate and must have a least four years of engineering experience to be eligible to sit in the EIT exam. Pass rate for Civil Engineers is 75%. The exam fee is US$ 80

Oracle Primavera

It is a must-know software for every Civil Engineer. Primavera allows detailed planning, execution, tracking and monitoring of project work. 

There are huge benefits of using Primavera, and every Civil company whether in US or abroad requires its employees to know Primavera. If you want to learn Primavera, I recommend the best and easy-to-follow books to learn the software, here.

Once the training is obtained, one can sit in the Oracle Primavera exam, by registering online at oracle.com. The exam fee is US$ 215 and it's a 105-minute exam, with 67% passing marks. There is no requisite to sit in the Primavera exam. 

PMI-SP (Scheduling Professional)

This certification is about scheduling concepts and teaches how to effectively plan and monitor project work, using different tools, techniques and methods.

The exam is held at Prometric testing center. One can register for the exam at pmi.org. The exam fee is US$ 670. You can read about the benefits and scope of PMI-SP certification, here

The Boeing 777x is expected to be seen in the space from 2020. The 777x will come in three variants: 777-8, 777-9 and 777-10x. Making of the 10x version is only proposed and not finalized yet. All the versions of the  Boeing 777x airplane will have new engines, new design and new technology for more efficient flying and better passenger experience. Read on for interesting Boeing 777x facts.

Boeing 777x Facts

1. Boing 777-8 and 777-9 are coming out to compete with Airbus A350, and the 777-10x is intended to compete with Airbus A380, which is the largest commercial airplane now.

2. The newer design will have higher ceilings, larger windows, increased humidity and cabin pressure for even better breathing.

3. This will be the 1st ever airplane to have folding wing-tips. This is to allow the plane to have shorter wingspan when it is moving on the runway.

4. Orders for 306 Boeing 777-8 and 777-9 airplanes combined have already been placed by Qatar Airway, Emirates, Etihad Airways, Lufthansa, Cathay Pacific and All Nippon Airways.

5. The Boeing 777x will use General Electric's engine GE9x that will burn 10% less fuel than the older engine models.

6. The Boeing 777x will be the first ever airplane to have touch-screens in the flight deck.

7. The 777x is going to be the world's longest commercial airplane ever.

8. The primary structure material for the 777x will be made in Al Ain, UAE, rather than at the native airplane material production units in Europe.

These were the facts about Boeing 777x. Hope you enjoyed them!

Almost everyone of us would have seen ships and boats sailing in water but how many of you ever thought about the science behind it. Isn't that strange to know that heavy steel ships don't sink in water whereas a small metallic pen sinks down? So, why do ships not sink in water, read on to find out.

No doubt the floating boats have signs of some Supernatural creator in them. He holds the heavy navigational traffic in water. But what is the mechanism behind it?

Mechanism Behind Floating Ships

Two main factors in ship design keep the ship floating:

1. Weight of ship (loaded and unloaded).

2. Shape of ship.

The ship designers calculate the weight of loaded ships and compare it to the weight of the water that will be displaced when the ship is placed in the water. The more water that is displaced, the higher the ship will float (i.e. in theory, if you keep loading a ship, its weight will exceed the weight of displaced water and it will sink).

Buoyancy

The tendency of a body to uplift an immersed body, because of the upward thrust of the liquid, is known as Buoyancy. The force tending to uplift the body is called the Force of Buoyancy or buoyant force and is equal to the weight of the liquid displaced. When a body is immersed wholly or partially in a liquid, it is lifted up by a force equal to the weight of liquid displaced by the body. This statement is known as Archimedes Principle.

According to Archimedes Principle:

An object floats when it has displaced its weight in the medium, in which it is floating. A large ship is hollow and big and easily displaces its weight in the ocean or fresh water. That's why it floats easily and not sinks in water.

Conclusion

1. If the force of buoyancy is more than the weight of the liquid displaced, then the body will float.

2. If the force of buoyancy is less than the liquid displaced, then the body will sink down.

More simply, if the volume of water displaced is more than the volume of object, the object will float.

Now you know why ships don't sink. That was interesting to learn about Buoyancy, that's the law create by God, this is indeed very amazing.
