Our cyclone separator is operating with Dcut=5μ. It is now necessary to increase the flow rate to the cyclone (and hence the inlet velocity) by 25 percent (i.e., the new velocity will be 1.25 times the old velocity). Nothing else will change. The cyclone is believed to obey Eq. (9.18). Estimate the new cut diameter.

Inventor of LED
When Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, or LEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights and other everyday technology.
On April 23, 2004, Holonyak received the $,500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the 10th year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors.
"Anytime you get an award, big or little, it's always a surprise," Holonyak said.
Holonyak, 75, was a student of John Bardeen, an inventor of the transistor, in the early 1950s. After graduate school, Holonyak worked at Bell Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches.
Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDs he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and cost effective.
Holonyak, now a professor of electrical and computer engineering and physics at the University of Illinois, said he suspected that LEDs would become as commonplace as they are today, but didn't realize how many uses they would have.
"You don't know in the beginning. You think you're doing something important, you think it's worth doing, but you really can't tell what the big payoff is going to be, and when, and how. You just don't know," he said.
The Lemelson-MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award for her work on a new generation of "molecular sieves," that can separate molecules by size.
Holonyak's colleagues thought he would fail in his research on LEDs at the time when he started it.
A.Right
B.Wrong
C.Not mentioned

The name Hallowe' en comes from the original "hallowed" (or holy) "evening". Many of the customs of Hollowe' en date back to ancient times when people believed in magic and superstition.
In ancient Ireland, people believed that on this night the dead could return to earth as witches, ghosts, black cats or in other strange forms. These creatures would perform. all sorts of wicked mischief. They were creatures of the night, and any form. of light was a protection against them. People made special lanterns, which they placed by windows and doors to keep the evil spirits away. In time, these lanterns came to be made out of hollowed-out pumpkins with a scary face carved on one side and a candle placed in the center. These are known as "Jack-o'-lanterns."
Hallowe' en superstitions were brought over to America in the nineteenth century and have now been trans formed into a creative seasonal celebration. Children dress up as ghosts and witches. On the evening of October 31st, they nm from house to house calling out "nick or treat." Neighbours give them candy ("treats") and if they do not the children might play a "trick" on them, like dusting flour over their doorstop; or making a lot of noise outside their windows. Adults also dress up and go to costume parties where they might receive prices for the best or scariest costume.
People decorate their houses with cut-outs of ghosts, witches, skeletons and spiders' webs, as well as beautifully carved pumpkins. Stores sell all sorts of goods in the typical Hallowe' en colors of orange and black. You can also buy pumpkin pie, pumpkin cookies and even pumpkin ice cream!
Hallowe' en might began in ______.
A.the 19 th century
B.ancient Ireland
C.America
D.England

Schooling and Education
It is commonly believed in the United States that school is where people go to get an education.Nevertheless,it has been said that today children interrupt their education to go to school.The distinction between schooling and education implied by this remark is important.Education is much more open-ended and all-inclusive than schoolin9. Education knows no bounds. It can take place anywhere,whether in the shower or in the job,whether in a kitchen or on a tractor.It includes both the formal learning that takes place in schools and the whole universe of informal learning?The agents of education can range from a revered grandparent to the people debating politics on the radio,from a child to a distinguished scientist.
Whereas schooling has a certain predictability,education quite often produces surprises.A chance conversation with a stranger may lead a person to discover how little is known of other religions.People are engaged in education from infancy on.Education,then,is a very broad。inclusive term. It is a lifelong process,a process that starts long before the start of school.and one that should be an integral part of one’s entire life.Schooling,on the other hand,is a specific,formalized process,whose general pattern varies little from one setting to the next.
Throughout a country, children arrive at school at approximately the same time.take as.signed seats,are taught by an adult,use similar textbooks,do homework,take exams.and soon.The slices of reality that are to be learned,whether they are the alphabet or an understanding of the workings of government,have usually been limited by the boundaries of the subject being taught.For example,high school students know that they are not likely to find out in their elasses the truth about political problems in their communities or what the newest filmmakers are experimenting with.There are definite conditions surrounding the formalized process of schooling.
There is no difference between schooling and education in the United States. 查看材料
