Q: How to convert kVA (kilo-volt Ampere) to kg/h (kilogram per hour) for diesel generator set (genset)? I want to know the relation about the energy produced (kVA) to the fuel that used (kg/h) in the genset, either it used more diesel fuel or not. i.e the kVA amount produced is 106kVA and the rpm is 1500rpm: You cannot convert KVA to kg/hr. KVA is a unit for power (rated capacity) and kg/hr is the unit for mass flow rate. There is no direct relation between them.

Q: I heard about the reactor and could someone tell me the story and what could happen thx.: Without getting to technical the current situation was caused by an event driven cascade failure.(think of a line of dominos.the 1st one knocks over the 2nd, etc and they continue to fall until something stops the reaction) The earthquake caused the tsunami. The tsunami flooded the diesel generator facility.(the generators provide back up power to run the cooling system. The secondary back up system failed. (batteries) Electrical power from other sources could not be rerouted back to the stricken site due to the damage to the lines. Everything that could go wrong did and the result is the hydrogen laden steam released into the containment building exploded. And,without constantly circulation the cooling water is/has boiled off and the reactor vessels are beginning to fail. As the other answerer said, read several articles about the event. Avoid the tabloids go for hard news this event has the potential to be worse than the Chernobyl meltdown. Hope I've been helpful. Google search phrases that might be of use g e reactors japan or g e reactor type at japanese site

Q: I have to wonder. WHY don't we have a car right now in 2010 that gets 100+ mpg?Ok we have the Honda Insight and Toyota Prius that get 50MPG+ WELL why not DOUBLE or TRIPLE or QUADRUPLE the Batteries and get 100MPG??? Seriously WHY NOT PACK Enough Lithium Ion batteries in there to get 300MPG?? You mean to tell me that with all the technology we have today in 2010 that we can't come up with a Hybrid that gets 100MPG??? PURE NonsenseSomeone somewhere is keeping the 100MPG car from being produced. Simple as that. You mean to tell me that you can't pack enough Lithium Ion batteries into a CAR to get 100MPG??? Yea right. You know it could be done. BIG OIL and other political forces DON'T WANT the 100MPG car. Why did gas prices go to $4.50 per gallon??? TO get the $$$ While the Getting was good. Now the gig is up and they know it.: Lithium ion batteries are a good source of energy storage, but they have some very serious drawbacks: If they are shorted they can go into melt-down and start a fire, and that's the small ones the size of a quarter. Think what could happen after a car wreck - You could start a block leveling fire. There will have to be a better battery design before the electric car becomes viable.

Q: i have 350kw old diesel generator and want to calculate the exact consumtionption at various loads.: You will need the specific fuel consumption of the engine, but it is probably close to 0.5 pounds per HP hour or 250g/KW.h. That is specified for the output shaft power at the operating RPM. It depends whether you have a turbo charger, the fuel a little, the air temperature and barometric pressure. Make sure exhaust and air intakes are not restricted too. You may find for a gen-set that you get a set of curves with the fuel consumption for different KW output. These account for the alternator efficiency already. Contact the engine supplier etc for this info. Use KWh from the generator (volts x amps x time gives KVAh not KWh). The amps might be up to 20% higher, depending on power factor of the load. The reactive part of the load does not need power from the engine. This is why I say to use KWh not KW, as you can use ordinary KWh meters (which ignore the reactive load). Allow for the efficiency of the generator (which varies somewhat, especially at light loads). Let's say 85%. Remember it is exciting the field, so that must be included in the efficiency. Thus if you are using 350KW for one hour, the engine provides 350KWh/0.85 411.8KWh (412KWh). The fuel used is 412KWh x 0.25Kg 103Kg of fuel. Now you need the specific gravity of the fuel you are using. You can call the fuel distributor. Ideally this is corrected for temperature of the fuel with the engine running, remembering the engine heats the fuel in the day tank due to recirculation. Let's assume 0.85 is the SG, so that means 0.85kg/l so 103Kg of fuel is 103/0.85 121 liters. In practice it may be higher, especially if the engine is old and worn. This answer is something like the maximum consumption, full rated output, 121 liters per hour. OR 26.6 imperial gallons or 32 US gallons per hour.

Q: I am trying to use a marine deep cycle battery and power inverter to power a chest freezer in an ice cream truck. The issue is that the marine battery will drain in a few hours. I was told told that I could connect the inverter to the car battery as well as the marine battery and while the engine is running, the car battery would be charge the marine battery through the inverter. Can anyone tell me how this works and how I should do the wiring?thanks: Just run heavy gage wire from one battery to the other, pos to pos neg to neg, no big deal, however your alternator ain't gonna like working that hard and will go see Allah in a very short period of time, so a high output alt will be needed sooner rather than later, and with the price of gas and seeing the shape some of those ice cream trucks are in, I see a lot of melted ice cream in your future. maybe a small generator would be more cost effective. almost forgot. if the wattage output of your inverter is not enough to power a freezer,which take quite a bit, you'll smoke the motor out of your freezer in a matter of days if not hours. yea lots of melted ice cream

Q: I inherited a never used generator from a family estate with no motor. After a tornado here last fall I've decided to build a gen-set with it and I have a few questions. 1) Does the 1800 rpm generator mechanical specification mean that the required engine rpm must be a minimum, maximum 1800 rpm or both? Could it be more or is the chance to ruin it a possibility? I want to stay safe.2) Obviously I'm assuming the 25 hp engine requirement is a minimum but how much bigger can it be without wet stacking problems?3) With these generator output specifications can I power my household without damaging anything?I was planning diesel (still researching brands) and connecting direct. Thoughts?: The generator probably has to turn at 1800 rpm to maintain the 60 Hz frequency spec. Thisis important in a TV set but I can't think of any where else it would be important. Slocks will be edpendent on line frequency but in an emergency you don' really care if you have a watch. Reet the clocks after the power returns. You will probably use minimum power during a blackout. You need light heat and a book which doesn't use much power. No Alfred Hitchcock or Ray Bradberry.

Q: Have a 15kw generator. Diesel. I want to upgrade without buying a whole new generator. Can I keep the motor and swap a generator hook up: The power of the diesel is matched to the electrical power rating. In theory, the Diesel requires 21hp to drive a 15kW output and is actually 25 (or more). The Diesel cannot deliver more electrical power. The oversizing of the prime mover (diesel) helps to absorb starting loads and prevent full throttle operation at rated output. In addition, specific exciter voltage is often drawn from the engine. The bell housing and couplings which join the engine to the generator are also likely to be specific. The chances of DIY improvement a slim.

Q: Hello im going to be a mechanic and i will have a 1998 turbo diesel H1 Hummer. Now I wanted to know since the hummer is not like a bus or a really heavy Diesel equipment that i can work on it myself like a regular car or do i have to have to be a diesel mechanic to even work on it?: No, it's ok for you to do your own work after you have had training.

Q: I have two deisel engines and two tank feeds, how can I connect the genset (4KVA) . I am conerned when the engines are idling or even running they will start the genset. I do not want to put an extra tank.Thank you: If your tank has another port on it for a fuel line that is where you hook up. If not go to the supply line at the tank and put in a T fitting and then a shut off valve for each engine. Run the supply line to the generator from that T. You will also need a return line from the generator that you can T into at the return line from the engine at the tank. Many people that convert from gas to diesels run into these same problems. Often a fitting is made up that is put in the fuel fill line to allow for the return line. The generator supply and return lines will be smaller then the engine fuel lines. Running the engines will not cause the generator to start.

Q: How much power does the generator from the diesel need to produce in order to bring the train up to running speed?: Power would be measured in watts (volts x amps) and for a diesel-electric loco it is going to be several thousand. A surge on starting to take up the train, then settle to optimum level as the train gets under way. Can't give you an exact figure as it varies according to different loco classes, load requirements, etc.
