I want to check the configuration of Hg

2007-02-15 20:11:54 · 7 answers · asked by Anonymous in Physics

I have an idea which can generate very considerable hydraulic pressure. I need to convert this hydraulic pressure into electrical generation. I need to know how much volume and at what pressure are required to drive an hydraulic motor connected to a 10kw generator 24 hours/ day. I need a design of specific components which are available and which could be assembled to produce this. I need to start this component series with the accumulator. an accumulator is required since the sourceflow is inconsistent. additional component assistance requirements will follow after this portion is solved. thanks.

One way of keeping warm on a cold nite, in the days before electric blankets, was to take a hot water bottle to bed.
A) If a hot water bottle contains 1.00kg of water and when in the bed has a temperature of 90 degrees celsious, how much internal energy will it lose as it cools to 25 degrees celsious??

I have been on the percocet for about three months. I am still having a hard time walking for long periods of time, bending over is almost impossible, and I still have a tremendous amount of pain. My doctor says that it is policy that they treat you for 90 days after surgery, then you no longer receive the pain meds. I only have a two day dosage left. I need to know how I can detox myself without dying. I don't snort them or anything or take them to get high, but it doesn't really matter why you were taking them, the withdrawals are the same, right? Anyway, any advice on how I could make the ordeal less suffering would be appreciated. Thanks!

I would like to understand how thrust contributes to verticle lift. How much thrust do my legs have to produce to lift me 1 meter off the ground or 10 meters or 100 meters etc. What is the formula that will tell me Xthrust will propel Xkilos from the ground Xheight.

why are certain buildings and interior designs pleasing to us? i heard of some sort of relationship of numbers, a so called law of numbers, that applies to architecture and design, because it is repeated again and again in nature.

please tell me about this 'law of numbers,' and show me diagrams in links, as well as examples of, how the law of numbers is found in nature, therefore, how designers and architects follow it?

is there any true merit in this? if an architect does not use them, will it cause the structure to have less strength, or less popularity?

does this law of numbers also apply in any way to shapes in solar systems / galaxies?

What is the reason behind rooster's eggs??
I know alot of ppl will respond saying they don't, so please don't reply if that's what u think. I know they do, because in my lifetime we had two roosters who laid eggs. the eggs were not regulary laid, they happened a few times. anyway, the size of the egg was too small in comparasion to our other hens (almost 2cm), and it did not contain any yolk, only transparent liquid. I just found out that some research labs were offering a large amount of money for a rooster that could lay eggs, too bad the roosters been dead for more than a decade. Anyway, i could not find a reason behind this phenomena. Is it genetic experiments that caused this rooster to lay eggs, or what??

Think about it. Everything in nature is perfectly designed. Just look at the Earth. If it were too far away from the Sun, we would freeze to death. If it were too close, we would all life would be destroyed by the heat. This can't be a coincidence.

Here's another proof:

Look at the moon. If it were too close, it would crash into the Earth and if it were too far away, it wouldn't orbit around the Earth. The moon is perfectly designed to keep asteroids from hitting the Earth.

All of this proves there is a God.

There are too many coincidences. Do you agree?
