I have three basic questions on compact fluorescent lights (CFL)

Are magnetic inductive ballasts, used in fluorescent lights, responsible for the undesirable lowering of power factor? Or do they...

Thanks for the help. I realize the CRT has nothing to do with the method of how the video is produced on the screen. I just used the term CRT to denote “oldness.” You are saying my old TV can display...

Thank you. I know my old CRT set can't reproduce progressive scan video. How am I able to view my progressive scan DVD player's output? It says right on the front of the machine it is a progressive...

I have a DVD player that says it is progressive scan. My older CRT TV however, is an interlaced scan device. It works just fine good picture, etc. using the DVD player. My question is how is...

The NASA Q&A site says: “The shuttles main engines develop 375,000 lbs of thrust at sea level and 470,000 lbs in the vacuum of space” According to NASA rocket scientists the reason for this is there...

Thank you. I totally agree. After doing some on line research I have come to the conclusion that having the jet under the surface would actually decrease the performance of the system. The reason...

That's right and also because centrifugal force is a fictitious force. What is called centrifugal force is really a manifestation or the result of inertia. Any time the word Centrifugal Force is...

And it woud be white, just like Elmer's Glue or mayonnaise both of which are emulsions of immiscible materials.

I have observed the propulsion jet nozzle on a JetSki or personal water craft is completely out of the water at plane or high speed. Why is this? What position produces the most thrust, above the...

The purpose of a dielectric union is to prevent electrolysis by electrically decoupling the two dissimilar pipes. If there is no current flow between them, due to the non conducting dielectric union,...

First of all the copper pipe I am talking about is not the ridged type used for water. It is flexible type "L" pipe. This pipe or tubing, if you prefer, is supplied in rolls of several different...

Hello
This is a natural gas application.
