Q:If electric vehicles included a generator they could charge the battery while moving. It seems the best choice to me.

Generators take energy to run. Thus putting a drain on the batteries.

Q:also is it probability that will damage my computer or UPS

Depending on where you live, your main power may occasionally be supplied by a large diesel generator. During power outages I use a 5500 watt generator to supply power to my home. The computer is on backup power and I have never had a problem. There is absolutely no reason for concern if you have a good quality generator that works properly. If your generator supplies a stable output voltage it will work fine. However if your generator operates near it maximum load and the output voltage varies in frequency and voltage there is a possibility of damage to equipment connected. A UPS may assist, but unless the generator is perfect the UPS will switch to battery power. After a short time the battery will run down and the computer shut off.

Q:I recently purchased a portable generator that is 7 hp and 3050 continuous watts, i tried to calculate the efficiency as follows:743 watts 1 hp7 X 743 5201 watts, (so at 100 percent efficiency, 5201 watts is possible to produce from a 7 hp generator.)the unit produces 3050 watts, so the 5201 watts (possible watts)/3050(actually produced watts) (0.5864) or approximately 59% efficiency, this does not seem right, it should be about half that.What am i doing wrong?

You are calculating only the shaft horsepower to electric power output efficiency. That is separate and different from the internal combustion engine efficiency. Calculate that by comparing the fuel used and its heat content and its ability to do work versus the shaft horsepower.

Q:How much power does the generator from the diesel need to produce in order to bring the train up to running speed?

That all depends upon a number of things. First is the type of traction motor that is driving the wheels. Next is the weight of the entire load to be moved by the traction motors. Also is the grade the load is being moved upon. When a locomotive gets up to speed it might not be using many amps by the traction motors to maintain the speed. However, to start from a dead stop on flat track with a very heavy load it could run as high as 200 or more amps. Again, it also would depend upon the number of engines driving the number of generators driving the number of traction motors. A single locomotive might need to use more amps to get up to speed than a combination of locomotives hauling the same load. There are many variables to this question. Given a particular locomotive, types of traction motors, the load weight, it would be easier to calculate what would be needed in amperage. Everything depends upon all of these things. An engineer can burn up a traction motor(s) by exceeding the amount of amps maximum that the motor can handle. The generators don't care, nor do they figure into the problem. The diesels don't care either. They will just turn the generators faster with more RPM's, and the faster they run, the more the generators will produce, but will the traction motors handle what is given them?? It just depends .

Q:I want to buy a portable generator for power-outages and need some advice on which to buy. I want to run: at least one refrigerator possibly a stand-alone freezerbasic lightinga few outlets a sum-pump. I also need to provide power to my heat in the winter Our heat is natural gas but it needs to be lit with the pilot light and I guess the thermostats need power. Preferrably diesel so we can store fuel safer. How many volts and watts do I need, what price range should I look for, and how many gallons of fuel would I need to be prepared for a good 2 days without power? Thanks- best answer gets the 10!

A 5000 watt generator will normally supply most of what you need, a 3500 will give a little more trouble with overloads, but will be quieter wihen not loaded. That Yamaha is a nice generator, if your the type that drives a MB S-Class, if you drive a Ford, you may want to be looking at a $700 Generac brand generator, fuel consumption will vary with load, but running at near capacity will burn a tank (5 gallons) of fuel in 8 hours, the higher the consumption of a generator he bigger the tank they put on. May want to check to see if Fridge and freezer are on opposite legs of your 240V service. FYI: Many electrical panel companies now make bolt in transfer switches to make any circuit in your house available to a generator rather than a gentran that just allows a few circuits

Q:I want to calculate the Genset load of following 3 phase, 50 C/s, 400/ 440 volts electric motors coupled with Water pumps.60 HP x 4 Nos. + 100 HP x 3 Nos. + 225 HP x 3 Nos.What is the method for calculating the safest load for all these motors to run simultaneously.

You are after capacity of the generator not load. You add up all the power required: 240 HP + 300 HP + 675 HP 1215 HP 1 HP 746 W Power required 906.39 kW You take this figure in consideration to choose your set allowing for efficiency and power factor.

Q:Having lots of diesel fuel to make electricity (200-800KW)is it better to use a diesel generator or a steam turbine?(Remember : the only way to produce steam is burning diesel)Does anybody know how many KWh can make per 1000gal?

Q:I Have an ASUS A8N-SLI Deluxe motherboard with the chipset fan going at over 6000 RPM, an AMD Athlon 64 4000+ with the CPU fan at about 3000 RPM, and a GeForce 6200LE with a very high pitched fan that's dead annoying. To cut a long story short, my PC makes way more noise than it should be, now I don't have any case fans installed but that shouldn't mean that it has to make this sort of howling, believe me, if you were sitting next to it, you'd understand where I'm comin from, it's like tryin to sleep at night with a diesel generator in your room while it's downloading stuff. The fans shouldn't need to spin that fast as the average temp is about 30-40 degrees Celsius across all the components. Anyone know what I should try? Cheers Sam The Bam

I had this problem, and one day, my computer just stopped. in fact, its sitting in the chair behind me. but it ended up being the CPU fan, put some thermal paste between it and your motherboard. Check your local Best Buy or Office Depot. but whatever you do, DO NOT TRY TO UNPLUG THE FAN! i did and my computer caught on fire (its not funny :[ ). And as a matter of fact, i can sleep with a diesel genereator beside me fine, im used to the noise, i sleep with a fan. ffs.

Q:A diesel-powered generator with a cost of $145,000 and estimated residual value of $7,000 is expected to have a useful operating life of 75,000 hours. During July, the generator was operated 150 hours. Determine the depreciation for the month.

145,000 - 7000 132,000 / 75000 1.76 per hour July 150 hours x 1.76 per hour rate $264 Keep in mind I rounded the $1.76 but if you follow this procedure it will get you where you want to be. I hope this helps and wish you all the best. good luck

Q:Electricity for all the computers, controls, and sensors and everything. Is electricity for these devices supplied by the nuclear reactor itself, or is it from an outside source? I've heard something about an emergency diesel generator but that's probably something else.

Credible? How's this I carry a Q point secure practices clearance from the U. S. NRC. I worked in nuclear vegetation for 2 years. the main section of the sequence to generate ability type nuclear capability is the reactor center. in the middle, a self-conserving nuclear fission reaction is going on. The splitting of the Uranium 235 nucleus via a neutron motives the ejection of two neutrons which in turn, splits 2 extra nucleus'. alongside with the neutron ejection is the releases of a extensive volume of capability in the variety of warmth. A coolant, regularly water is circulated below severe tension to this center. The tension facilitates the water to learn warmth capability yet stay a liquid. After the coolant leaves the reactor containment section, the tension is suddenly decreased. This kinds steam, that's used to coach extensive turbines related to the two superb turbines. those create the electrical powered ability. The expended decrease tension steam is condensed and then returns to the middle to do the cycle lower back.
