If a 20 HP steam engine needs 200psi of steam to run, will it run on 200psi of compressed air ?

The answer may be yes or no.  The 20 HP steam engine either exhausts to atmospheric pressure (wasting the steam) or to a steam condenser (which recovers the steam for reuse and produces a much lower discharge pressure).  Onboard seagoing vessels, triple-expansion reciprocating steam engines used the lower discharge pressures produced by a condenser to extract more mechanical energy from the steam.  Almost all steam turbines onboard a ship also discharge to steam condensers to extract more energy.\n\nTo be comparable to a steam plant with a steam condenser, the "air-driven" steam engines would have to discharge into vessels maintained under partial vacuum by huge vacuum pumps.  Therefore the air and steam driven engines might produce similar amounts of mechanical power (and torque) but would likely differ because of the thermodynamic properties of air as opposed to steam.\n\nThe steam engines derive power from water heated in a boiler fired by an oil-consuming furnace.  The "air driven" steam engine would require a huge air compressor and vacuum pump to operate (but that was not your question?).\n\nAnother important consideration is that the steam is very hot and contains more energy than air at the same pressure (unless the air is also heated?).\n\nYour question is very interesting but the answer is not all that simple.  Hope this helps a little.

Yes but first your engine should be in good running order. If your engine is clogged or just runs like S#@T then it won't help much.

it depends on the type of your veachile. the safest turbos are run at 8 PSI

No,instead of cooling the room get heated up.\nthe compressor will have to do much work and heat will be given out.

There is a boiler in Nuclear Subs, and a diesel engine in (obviously) diesel subs. The steam pressure from the boiler pushes through a set of mechanical turbine fans, which have output shafts driving a set of small gears. These small gears turn a large one, called the bull gear, which reduces the speed of the screw, or the impeller part (the big fan that spins) of the "hydrodynamic propeller", in order to provide torque (strength). If the propeller were to turn at high speeds, it would "tread water", because the low pressure it creates would be enough to vaporize the water (this is called "cavitation". The propeller would be simply stirring up steam and have no push. So the propeller has alot of strength at low speeds and is very large. It can push on an extremely large area of water. The water does not move, due to laws of inertia and mass, and gives the submarine something to push against, and therefore allowing it to move forward.\n\nA vague representation of this ability is the little experiment where you put a ruler on the edge of a table, and put something small and heavy on the end that sits on the table. Slap down on the end hanging off, and watch the object go flying. Next, spread a sheet of newspaper over the ruler, all the way to the edge of the table. Now slap down on the ruler again, and if you it hard enough, you will either break or bend your ruler. This happens because, thought the newspaper is much lighter than the previous object, it has the entire area of air above it, which has mass. The surface area of the newspaper is large enough to distribute all of the force to the mass of air, and, because of the law of inertia, the air holds the newspaper down.\n\nIn a diesel sub, it is basically the same concept, except that there is a direct drive between the engine and the small gears.

almost certainly it's in the US code of federal regulations (CFR).  it seems to depend on the type of boiler you use - is it a boiler for waste disposal, steam heating, on a ship or a locomotive, etc?  the answer determines which section of the code is applicable.\n\nyou should probably use the search engine at http://www.gpoaccess.gov/cfr/index.html .\n\ngood luck!

Yes the low steam temperature improve the condenser vacuum because the density of the steam will decries and the vacuum efficiency will increase.\nBut you will face another thing the at the low pressure turbine (LP) exit, the moisture will increase and the work of the turbine will be little down!!

I would suggest contacting the manufacturer (or CO2 supplier) then consider whether your application is more or less critical and thus may be covered by industry codes.  There is high pressure and then there is high pressure and your specific pressure, environment and use (pressure cycles?) may be important.  If there were an accident or interruption of CO2 service, you might be liable for not following codes or using good judgement (backed up by your formal contacts?).  Also, can the CO2 supplier furnish you with tested cylinders to avoid contaminating them with hydro fluid?

Of course.  But before doing that check the currents that are required for the load.  Usually, appliances running at 12 VAC are also low power, and those that run at 230 VAC are high power.

What do you mean by 'rebuild'?  What is wrong with the motor?  For a 20 HP, I would guess that it is cheaper to buy a new one unless it is a very unusual motor.

An air compressor is a machine, usually made up of a piston connected to a crankshaft and moving in a valved cylinder (a mechanism similar to a piston engine), that takes in atmospheric air and compresses it to a higher pressure. The output, compressed air, may be stored in a pressure tank or may be used directly in air tools, dust-removal nozzles, paint sprayers, or to inflate tires (among many other uses). The compressor requires a source of mechanical power to operate. Probably the most-used type is a unit consisting of electric motor, compressor and tank with pressure gauge. See the ref. for a description of how they work.

steam has more energy in it. steam is derived from heating water up, so steam will contains much more energy and thus translate to a more powerful turbine .

200 W is not much for modern computers.  I assume that if you don't add anything, things keep working.  The power supply need not explode or catch fire.  More likely the voltage levels drop under overload, and things stop working.

It justs super heats the steam defined as the heating of a fluid after reaching its boiling point. If you have more doubt on this feel free to mail me. But if the questions are seriously done.

i think efficiency is expressed as ratio of power inputed/power outputed\n\nie if the compressor was rated at 800w( uses 800w) and gave out 800w in useable power then its efficiency is said to be 1/1 or 1, but no machine is that efficient, due to heat , vibration and friction etc.\n\nif the compressor was rated at 800w and gave out 200w of usable energy it would be an efficiency of 1/4 or 0.5

At 20 degrees C, it's 0.6g/100mL. You can convert that to a Ksp.
