Physic problems serious answer please 10 points?
1) How much pressure must be produced in a cylinder with a diameter of 10 CM that moves 5cm after an explosion in the cylinder doing 1000 joules of work. IF the temperature in the cylinder is 450 °C What is the maximum efficiency on a sunny day where the temperature is 35°C ? 2) […]
Science question please help 10points and best answer ?
All of the following power plants are considered thermal power plants because they heat the steam that works the generators, except a.nuclear power plants b.coal burning power plants c.fossil fuel power plants d.hydroelectric power plants
there are lots of hydrogen generators on the internet.. do they work. what are the pros and cons?
they all over heat and make mostly steam. most have no control of power used. as it gets hotter it pulls more power, as it pulls more power it gets hotter and snow balls out of control. when amps get over 30 the strain on the alterator costs you gas to run it. it cant […]
What is the purpose of large hyperboloid cooling towers at power plants? It is just going to be steam again.?
I realize these impressive structures are to cool water. Presumably to cool water that is circulating through the whole system as steam, water, steam, etc. that is making the turbines spin and thus the generators. What I don’t understand is why cool it at all? Isn’t it headed directly back into the boilers to become […]
How do electric generators work?
Including steam turbines that egenerators work w/. and power plants using fossil fuels, coals, oils, nuclear power, wind, hydro power, solar power, and tidal movement.
Which would make more sense? Converting diesel electric trains to biodiesel, or?
creating steam turbines that can run on ANYTHING to power the electric generators in modern engines?
solar power question?
so solar panals are only about 4% efficient.. has anybody built a solar steam generator? and if so how efficient/feasable is it?
Where do the electrons come from?
My space heater pulls electrons from the “hot” lead in the wall socket, into a ceramic resistor that heats up and leaks the electrons back into the wall socket on the “cold” lead. That cold lead is connected in my garage, through the fuse box, to a copper spike driven into the ground. So, that’s […]
Why isn’t it possible to use water as fuel for cars?
To those more knowledgeable about these types of things, this may seem like a “dumb” question. However as a non-scientist it makes perfect sense to me. 1. Suppose one had an ignition system that completes a circuit allowing current from a battery to heat a heating element for a boiler full of water. Or… initially […]
Work required to compress a gas vs. liquid?
Generally does a compressor use more power to compress water vapor or does a pump use more power to compress liquid water as represented in the following two processes. Initial state: saturated liquid, Final state: superheated vapor (same for process one and two) process one: initial state->pump->steam generator->turbine->final state process two: initial state->steam generator->compressor->turbine->final state […]
Would it work? & if so would we still need to use oil?
A hybrid Engine that uses solar power to warm the electric coils which boil water that powers a engine( a steam engine) this could be a Generator in theory or a car engine … IT would also have fans that gather electric power through the wind for other purposes or surplus. if only they could […]
Kinetic theory help please?
please may you help me with this question Explain, using the kinetic theory, the changes which take place in the steam generator vessel as the water is heated rom a liquid to a gas, increased in ressure by increasing temperature and then cools baqck to a liquid. Be sure to gie a ful explanation of […]
Generating power directly from heated water?
I fully understand the concept of a steam driven turbine to generate electricity (use of steam to turn turbine, which drives a generator to produce electricity), however is there a way of directly harnessing the potential energy in heated water (i.e. water in a supercritical state) without the use of turbines? If there are no […]
i want to be able to generate enough electricity to power my home with the use of steam engine who can help me
in case of power disruption due to bird flu i believe steam engines that are wood burning combined with generators will work well because fire and water are plentiful
In a nuclear power plant, the heat from the reaction is used to make what?
This is one of my homework questions. Dealing with nuclear things. I think in this case, it is talking about nuclear fission. The answer is either water, steam, oil, or generators. Help?
Why don’t we utilize the heating power of volcanoes to make thermal electric power stations?
Turning the generator makes electricity, generator is turned by turbine, and turbine is turned by force: the force is either water from waterfalls or steam. Boiling water creates steam. Water is boiled by coal, natural gas or atomic power. Why don’t we use the heat form volcanoes? This question is for scientists, who can think […]
Is this really the answer to the world problem?
I seen a blog about a patent that GM owns. It is a water powered car. I think the way it works is steam generated by a microwave device is injected into the combustion chamber then ignited by a spark plug. Kinda like a mini lightening bolt. after the engine warms it generates its own […]
Are there any fatal flaws with this idea?
I would like to see a power plant that sits on a sunny beach. This power plant would have a massive solar panel array that would not feed it’s power into the grid but would be used to power many Electrolysis machines. The machines would extract the hydrogen from sea water and use it to […]
Engine that burns powdered solids?
Is there a commerical mfg who builds engines which can burn solid fuels, powderized, such as coal, biomass or such fuel? Without having to burn it in a boiler to make steam to power a turbine to run a generator? Not just little 5hp or 10hp engines but bigger ones from say 200hp up to […]
