The new king of moons “Saturn “




Jupiter vs. Saturn who’ll win ?


In 7th of October 2019 Carnegie Mellon University for sciences said in 

its report that a team of Astronomy scientists in the university 

discovered a new twenty moons orbiting around Saturn 

in addition to the old sixty two moons by using subaru 

Telescope in  Hawaii state .  Scott Sheppard from Carnegie University  for Science led the discovery team. He said in a statement:

Using some of the largest telescopes in the world, we are now completing the inventory of small moons around the giant planets. They play a crucial role in helping us determine how our solar system’s planets formed and evolved. 

and now by this it has eighty two moons and so it 

Outperform Jupiter which was the king of moons by 

seventy nine moons .

Nasa said that:Saturn has 82 moons. Fifty-three moons are confirmed and 

named and another 29 moons are awaiting confirmation of discovery and 

official naming. Saturn's moons range in size from larger than the planet 

Mercury — the giant moon Titan — to as small as a sports arena. The 

moons shape, contribute and also collect material from Saturn's rings and 

magnetosphere. 

According to the researchers, each of the newly discovered moons is about 3 miles (5 km) in diameter. Seventeen of them orbit Saturn backwards, or in a retrograde direction, meaning their movement is opposite to the planet’s rotation around its axis. One of the newly discovered retrograde moons is the farthest known moon around Saturn.

The other three moons orbit in the same direction as Saturn rotates. Two of these three moons are closer to the planet and take about two years to travel once around Saturn. The third, and the more-distant retrograde moons, each take more than three years to complete an orbit.

The outer moons of Saturn appear to be grouped into three different clusters, according to how they orbit the planet. The newly discovered retrograde moons appear to belong to a group of moons, named after Norse mythology, thought to be fragments of a much bigger parent moon that was smashed to pieces in the solar system’s violent past. Sheppard said:
This kind of grouping of outer moons is also seen around Jupiter, indicating violent collisions occurred between moons in the Saturnian system or with outside objects such as passing asteroids or comets.

NRLT MODEL (NON-RANDOM TWO LIQUID)

“Process design “ NRTL MODEL   (NON-RANDOM TWO LIQUID) NRTL MODEL IS a one of fluid package in HYSYS it is belongs to  activity model . The   Activity Models handle highly non-ideal systems and are much more empirical innature when  compared to the property predictions in the hydrocarbon industry. Polar or non-ideal chemical  systems are traditionally handled using dual model approaches.  The Non-Random-Two-Liquid (NRTL) equation is an extension of the Wilson equation.It uses  statistical mechanics and the liquid cell theory to represent the liquid structure. It is capable of representing VLE, LLE, and VLLE phase behaviour.  The NRTL property package is used for chemical systems and HF Alkylation with highly non-ideal chemicals. NRTL uses the following calculation methods:  For liquid:  • NRTL method for VLE  • Cavett method for Enthalpy and Entropy.  For vapo...

the rains in different worlds

صورة
Have you ever asked if it rains water in the another planets like earth or not?  Is there any rains in space? That's what we'll know in this post . While it may not rain in space, other planets do experience their own forms of rain. On Saturn's moon Titan, liquid methane and ethane falls to the ground like water on Earth. In fact, liquid methane lakes on Titan's surface allow a methane cycle that's similar to Earth's water cycle.  And Did you know if you want to be rich you only need to go to Uranus or Neptune 😯 I'm just kidding 😁 Yes because in Uranus and Neptune rains diamonds . It rains solid diamonds on Uranus and Neptune. Consider this your daily reminder that the solar system is even more awesomely bonkers than you realized: On Uranus and Neptune, scientists forecast rain storms of solid diamonds. The gems form in the hydrocarbon-rich oceans of slush that swath the gas giants' solid cores. Also On Jupiter, helium condenses into drops of liquid a...

POLYURETHANE

Polyurethane • Polyurethane, any of a class of synthetic resinous, fibrous, or elastomeric are compounds belonging to the family of organic polymers made by the reaction of diisocyanates (organic compounds containing two functional groups of structure −NCO) with other difunctional compounds such as hydroxyl . • Otto Baer and his colleagues in Germany first manufactured polyurethane in 1937. The one of polyurethane disadvantages it is a flammable solid material and when we burn it by fire it will produce high quantities of ( CO, hydrocyanidein ,in addition to nitrogen's oxides, isocyanates , and other toxic products). It Consists of linked organ units with urethane radical . This polymer is has a very wide using especially in industries everything surrounding us which has an insulation, corrosion &( cooled , heat) resistance properties is almost consists of polyurethane. PREPARATION: Polyurethanes are made by the exothermic reacti...
