How much thermal energy does the plant generate in one year?
Q. A typical nuclear power plant generates electricity at the rate of 1060 MW. The efficiency of transforming thermal energy into electrical energy is 1/3 and the plant runs at full capacity for 76% of the year. (Assume that this nuclear power plant is down about 24% of the time for maintenance and refueling.) (a) How much thermal energy does the plant generate in one year? (b) What mass of uranium is transformed into energy in one year?

A. If q=1060MW Watts are Joules per second, you want joules (or watt-hours perhaps) find how many seconds there are in a year, multiply this by 1/3), then multiply this by .76 This gives you the seconds of production. Multiply this by q to get watts*seconds which is Joules. I'm not sure about the energy transfer from uranium though. E=mc^2 might help

How is thermal energy converted to electric energy in a fuel cell?
Q. I understand how the energy of fuel is converted to thermal energy in a fuel cell, but what mechanism is used to obtain electrical power from the generated heat?
Asked by Huguette - Thu Dec 25 16:52:16 2008 - - 4 Answers - 0 Comments

A. I am going to give a rather simple explanation by simply saying that most of us remember a high school experiment in which we separated water into its 2 parts of Hydrogen and Oxygen. This was done with a certain amount of electricity to power the electrodes. The fuel cell merely takes some Hydrogen and combines it with available Oxygen from the air and converts this back to water. If that process were 100% efficient then ALL of the electricity used to separate the H and O in the first place would be recaptured by this reverse chemical process. Some of the electricity is lost in the form of heat so the process is not perfect but way more of the Energy is captured this way than by BURNING the hydrogen as a fuel.

What is the best thermal under glove for motorbike riders in minus degrees celsius?
Q. I suffer badly from frozen hands and feet when I ride and no matter how much i spend on gloves (and I have bought brand names) they don't seem to keep my hands warm. I have purchased some thermal under gloves in addition but my hands still feel as if they've been slammed in a car door by the time I get to my destination. Please help.

A. I like your analogy about hands being slammed in a car door, that's great!! Gerbing makes electric glove liners as well as a whole line of electric gloves. Another option is electric grips. I have them on one of my bikes and are very pleased with their performance. one more option are Hippo Hands that slide over the end of your bars that cover your hands and creates a pocket of still air so there is no wind blowing across the gloves.

What does mechanical and thermal energy have to do with Global Warming?
Q. I am doing a project about the conversion that take place in Global Warming. I need to figure how heat, mechanical energy, and thermal energy is converted.
Asked by Amelia S - Tue Jun 3 21:09:01 2008 - - 1 Answers - 0 Comments

A. Global warming is the theory that the earth is warming. There is little accurate data to support this, but historically we are very cold, almost as cold as the ice ages. So, likely we are warming. Anthropomorphic global warming is theory that man's activities contribute significantly or mostly to global warming. No evidence for that, but many people fervently believe in it anyway. Not clear what energy conversion you are talking about. Energy can have different forms. Two basic catagories are potential energy and kinetic energy. Potential energy is stored energy that can do work; kinetic energy is energy stored in the motion of an object. Classical examples are kid on a swing or roller coaster. As the kid or coaster reaches the top, speed… [cont.]

How much thermal energy is produced in the loop?
Q. I'm not sure how to incorporate time within the equations for thermal energy. I kept getting 6.0755E-7, but that seems wrong. A loop antenna of area 2.00 cm^2 and resistance 5.06 ueOhms is perpendicular to a uniform magnetic field of magnitude 20.0 ueT. The field magnitude drops to zero in 2.40 ms. How much thermal energy is produced in the loop by the change in field?
Asked by phuket_thailand25 - Tue Aug 25 14:58:16 2009 - - 2 Answers - 0 Comments

A. I hope the following helps, but I'm a bit rusty on the theory. When a change in the magnetic field induces electricity in a loop, we're working with Faraday's law, where it says: Electromotive force (EMF) = - (change in magnetic flux) / (time diff) Magnetic flux = magnetic field x area = (20 x 10^-6) x 2.99 x 10^-4 = 59.8 x 10^-10 EMF = (59.8 x 10^-10) / (2.4 x 10^-3) = 24.92 x 10^-7 V Power = V^2/R = (24.92x10^-7)^2/(5.06x10^ -6) = 122.72 x 10^-8 Energy = power x time = 122.72 x 10^-8 x 2.4 x 10-3 = 2.95 x 10^-9

What is the cost benefit of having thermal insulated windows?
Q. What do thermal insulated windows do and how much would it normally cut from your heating bill over having regular windows (for a small 1-bed apartment)?
Asked by LG - Thu May 10 11:13:23 2007 - - 1 Answers - 0 Comments

A. Insulated windows increase your efficiency by a factor of 1 over a standard window, which is not measurable. You will never pay for the window with energy savings. If the window is already broken and needs replacing-then you may consider an insulated replacement. However-you should still compare the cost of a standard window over an insulated one. If the insulated one cost much more-then do not buy it.

A. The best source of this data is the manufacturer of the material if they will give it to you. (Good Luck) The other two ways are to check all of the chemical literature to see if someone else has done it. Finally, you could do the experiments to determine it yourself. Remember what Edison or Bell or one pf those pirates said, "Three or four months in the laboratory can save you all of an afternoon in the library."

What are the thermal limit calculations in transmission?
Q. Hey everyone, i'm supposed to be gathering information about electrical power transmission, and my instructor told me to research about thermal limit calculations. i know the thermal limit is the result of the heat that is produced in the cables as a result of electricity loss, but i can't find any more information on the net. can you guys give me some ideas on where to look / what to look for?
Asked by banaf - Wed Jul 2 21:17:37 2008 - - 2 Answers - 0 Comments

A. The thermal limits for an overhead transmission line are where the conductor sag is at the minimum allowable clearance (either to ground or a lower circuit) The higher the load, the higher the temperature, the greater the expansion of the conductor and the greater the sag. The National Electric Safety Code defines the minimum clearances depending on circuit voltage and what is under the lines (navigable waterways, highways, fields, etc) If there are other transmission lines below this one, the NESC also defines the minimum clearance between circuits.

A. Convection means air is circulating and distributing the heat. Forced convection means a fan is used to circulate the air. Thermal oven is radiant heat source like a heat lamp or electric stove top. I have a convection oven and I think they are great. Much better than a regular oven.
