Are diesel engines more polluted than steam engines?
Of an individual diesel engine and an individual steam engine of the same energy output the diesel engine would be less polluting. It is far more efficient. However, there are far more diesel engines than steam engines in the world today so overall diesel engines pollute more than steam engines.
Is a steam heating system more economical than natural gas?
Steam heating is a legacy system left over from previous generations. It's less efficient thant modern heating systems. However it's often not economical to rip out a steam heating system and then replace it.
If high steam carbon ratio what will effect on reforming?
I'm guessing you mean high carbon to steam ratio. that gives rise to a proportionately greater volume of carbon monoxide being evolved. if there is a lot of steam and only some carbon, you normally get the more stable CO2 but with insufficient steam, the less stable CO is evolved, ALONG WITH some CO2. =]
To produce 5 MW of electricity how much steam pressure is needed and water in relevancy. What temperature is needed to produce it and what size pipe should be piped into the steam turbine?
That is a question that does not have one single answer. For instance, if the pressure of the steam is raised, less steam is needed. As pressure rises, temperature will also rise due to adiabatic work done on the steam. Also, higher temperatures are needed at higher pressures to make sure the steam does not condense. Raising the temperature of the steam at a given pressure also means that less steam is needed to provide the same amount of energy. Efficiency will also vary, depending on the turbine, and other factors, such ascondenser vacuum. In general, running a pressure around 40 - 45 PSI, it will take 20,000 - 25,000 pounds of steam per hour to generate one megawatt of electricity during that hour. This is with steam that is just above saturation (around 285°F). So, for 5 MW, you'd need around 100,000 pounds of steam an hour. The pipe size would depend on the turbine. A 55 MW turbine (common for geothermal), might have two pipes bringing steam in (one per side), both of which are around 30" in diameter. For 100,000 pounds of steam an hour, much smaller pipes would suffice. However, expanding and then compressing the steam repeatedly is something you want to avoid. Note that these figures reflect more of a geothermal application. The pressure and temperature of steam from a boiler will typically be much higher.
What is the steam engine's application today?
Most steam engines except those used on tourist railroads have been replaced with the more efficient steam turbine engines.
Is steam more dense than mist?
steam is less dense than mist because the particles in steam have more energy so they are less dense and rise. but mist is denser because it does not rise into the atmosphere and simply lurks around on the floor and has less energy
Where can you download working acclaim BOTS 2010?
You can't download Bots Acclaim anymore.It shut down,so Bots is no more.
Is the density of steam more or less than the density of water?
Humid air is lighter and less dense than dry air. Steam is water as a gas. Gaseous water is less dense than dry air.
What is the meaning of the idiomatic-expression 'peter out'?
The expression 'peter out' can mean something becoming less and less until there is no more; or for running out of energy and/or strength. Similar expressions for the second use are 'running out of steam' or 'out of steam'.
What is the steam spray iron?
An iron that uses steam to make to fabric more malleable before heating it to flatten it out
Are there more auto-bots or decepticons?
There are the same amount of auto-bots and decepticons , they're just scattered across the universe. It may seem like there are more decepticons.
Is pressure after throttling is more or less?
You cannot increase steam pressure through a valve without adding heat to it. Throttling steam always reduces its pressure.
Why is the steam turbine generally more efficient than the piston-type steam engine?
less moving parts, each of which subtracts from total energy output
Why was the internal combustion engine more satisfactory to motorists than steam or electric cars?
It cost less and it was more quiet.
How do you defeat the mini-bots on poptropica?
To defeat mini-bots you need to get them to charge to a yellow glowing ball and explode and watch out there are more!
Why does steam weigh less than water?
Both steam and liquid water are made of the same substance (H2O). However, in the gaseous form (steam), the molecules are moving more quickly, and they are spread apart much farther. As such, the number of molecules per given volume (the mass per volume) is lower for steam. Mass per volume is the same thing as density.
What is the best place to mine mithril in rune scape?
The "best place" will vary a lot, depending on how many other players go there. The Mining Guild used to be a good place. It was more or less ruined by bots (that is, it was hard to get any mineral with all the competition); perhaps now that there are supposedly less bots, it will work again. But you may also want to try some of the other places.
