2. Objective
1) To investigate of solid-liquid mixture flow characteristics in a slim hole annulus
2) Effect of pipe rotation, fluid property, annulus inclination on the particle transport velocity, transport efficiency and pressure drop
3. Theoretical background
3.1 Reynolds number
Reynolds number can be defined for a number of different situations where a fluid is in relativ
1 Introduction: Amazon.com
Amazon.com is a company founded in 1994, US. The name is from the world’s biggest river. Its logo represents a bent arrow from A to Z, which implies its will to deliver every product in alphabet to its customers. The bent arrow also represents customer’s satisfaction. Amazon.com began its Internet retail store service in 1995. At first, it only dealt with books, f
Gear A is constrained to roll on the fixed gear B but is free to
rotate about axle AD. Axle AD is connected by a clevis to the
vertical shaft DE which rotates as shown with a constant angular
velocity 1. Knowing that gear B rotates with a constant angular
velocity 2, determine (a) the angular velocity of gear A (10점), (b) the
angular acceleration of gear A (10점).
◆ Modern Society and Web 2.0
Web 1.0 era as the word of "sea of information", we are exposed to a lot of information. Regardless of distance and time, we can easily send information as well as our own private information. Also, the amount of data, in 1989, the European Particle Physics in Switzerland, developed hypertext and MOSAIC invented first web browser in 1993. Those changes helped to
connect the many
rooms and compartments within the compound. Sturdy, but
prefabricated materials have been used in its
construction.
There is a laboratory. An infirmary. A kitchen and mess
hall. A communications room and sleeping quarters. Other
cubicles are for storage and supplies.
The most spacious area of the building, and the main
center of activity, is the Rec Room. Of the many entrance
