Engineering - March 2007

I am planing to make a pressure maker on faucets that will help make a greater amount of pressure in order for the water to flow on a bigger pipe... the thing is I want to know how it works so I can plan how to make my pressure maker... I wanted to prove that it works... In addition to that, I want to know how to control the water when it gets out ouf the water spout... I really need help... The dead line of the submition of Chapter 1 (problem and its background) is near... I need to make a background of the study, statement of the problem, theoretical or conceptual framework and all others in a short while pls...

Thank you and God speed...

oscillators take dc voltages n produce an A.C without input signal while Power supply convert the A.C signal to DC signal. Do the two circuits work apposite to each other ?

Some states require an expansion tank installed with a pressure reducing valve with or without a bypass feature. California State code is not specific on wether this creates a closed system. I would like to know if a Pressure reducing valve creates a closed system even with a bypass feature? A pressure reducing valve is installed on the main water line from the supply to the home to reduce water pressure below 80PSI. It is similar to a check valve until the thermal expansion of heated water reaches the supply pressure to activate a bypass feature. Can you look on the body of the pressure reducing valve and be able to determine if it has a bypass feature?

I am trying to automate a new item setup process, where we have to calcuate the number of boxes that fit on each layer of a pallet. Our pallets are 48" by 52", and I would like to maximize the number of boxes per layer, while utilizing as much space as possible. Is there anyone that could let me know how this can be done? An example would be:
Product box is 26" Long and 19" Wide. The solution is 4 boxes per layer.

I'm thinking of starting a website and plotting stress vs. strain graphs of various non-engineering materials such as cheese, lettuce, paper, ice, etc. What do you think?

Speaking for a WELL WATER source, but it shouldn't really matter, I mean I know the "current systems" that they sell commercially do not really GO ALL THE WAY... i know that the system I am looking for wil perhapsl be expensive until it is mass produced. Anybody got any ideas. I am willing to INVEST MONEY in such a system which will produce 100% pure water no strings attached.

What kind of "system" do I need to insure PURE WATER?
Is there something electrical? What are the "realms" of ellectricity?

basics:
IMAGINE a water source that was PURE... it went thru PURIFIERS , FILTERS, UV light zappers, DISTILATION and condensers (and maybe other methods that I am unaware of)and the TAP is metered so that you can see it registers PURE.
THE ULTIMATE FILTER
