FAQ

1. Both fans are running2.Both fan is running 3.Both diesel generators were serviced 4.Both diesel generator was serviced5.Both diesel generators had been serviced. / Has been servicedWhich one is correct, and why?

These three are correct - 1. Both fans are running (are, because both fans is plural) 3.Both diesel generators were serviced (were, because generators is plural) 5.Both diesel generators had been serviced (you can also say have been serviced, if they've been serviced recently. EDIT.@Diane: None of them is singular; therefore is correct.and the question doesn't concern punctuation.

I know they are more expensive.

Yes. But they also burn much hotter in the SOFC.

I work at a high rise building as security and was interested to know why smoke would come out of a generator? What would be the main reason? Engine too hot? A snapped wire?

What kind of generator and how is it fueled? A diesel generator will smoke at start-up, and if it is an older unit burning old fuel, it will smoke in operation as well. That would be smoke from the exhaust. If you are writing about smoke from the windings - that is the generator itself - that would be due to an overload and/or winding failure, and caused by the system overheating. If you are writing about smoke coming off the engine - that could be from an oil leak, or debris falling onto the engine and being combusted by heat. Only the first of these is 'normal'.

I need a flowchart of the endergy conversions while popping popcorn. Example: Chemical energy to physical energy to nuclear energy, etc.

Starting from the pop and moving towards the energy source The kinetic energy of the popped kernel converting to heat when the kernel comes to rest. The kinetic energy of the kernel from the explosion due to steam and the steam escapes with kinetic and heat energy that transfers to the ambient air as the steam condenses and then the droplets fall and convert kinetic energy to heat. Potential energy in the steam as it builds pressure inside the kernel The transfer of heat from the burner into the popping vessel to raise the temperature of the moisture inside the kernel to make steam Where did the energy come from to heat the burner? I will assume it is electrical energy created from a diesel generator peaker plant nearby There is resistance in the burner heating element that converts the electric current to heat. There is also resistance in the wires and transmission lines and transformers that carry the electricity from the power plant to the burner, which is all lost to heat. The electricity is created from a generator where there is an wire-wound aperture spinning in the presence of a magnetic field. The kinetic energy of the aperture gets converted to the electrical energy and sent out on the transmission lines. The kinetic energy of the aperture is created inside a diesel engine by connecting it to the crank shaft - some friction losses due to bearing surfaces. The kinetic energy of the crank shaft is created from an explosion inside a piston. The explosion creates an expansion of gases that push the piston, which spins the crank shaft. Some of this energy is lost to heat dissipatin and friction. The explosion was from the conversion of the chemical energy in the diesel fuel to heat. The pressure in the piston caused the fuel and oxygen mixture to explode. How's that? j

I just got sworn in a few weeks ago to the navy, as an engineman. I was wanting to be on a carrier but didn't know if there was any jobs for the EN rate?

Most likely work related to the diesel generator or as an auxiliaryman. All propulsion work on a carrier is done by the NUCS. edit Enginemen are often assigned as small craft engineers, operating the engines on various boats carried by the ship.

I am currently a diesel mechanic in the Army. I know a lot about bothe gas and Diesel engines in cars trucks and generators. My contract is almost up and I m trying to transition back into the civilian world. I was just wondering if someone could help me out with any major differences between a 6.7 liter Diesel engine and the Diesel engines in heavy diesel trucks

They are bigger.

I intend to buy Diesel Generator sets in USA but the problem is that the Generator sets available in USA are 50/60Hz /1800rpm, pf 1.0 , 277/480V whereas in my country the Frequency is 50Hz , Voltage is 220/380V and power factor is 0.8. What shall I do to convert the US spec's to what is my requirement.

It is a fairly easy adjustment to make for most of the equipment, as manufacturers know that many people need 50 Hz power. Mention your needs to the company you are buying the generators from. They should be happy to perform/quote a conversion for you.

If i am using a permanent magnet dc motor as generator then how should i calculate how much electricity the motor will produce ? or lets say i want to produce 1kw power with permanent magnet dc motor then how much hp motor i shd choose

I'm not an expert on this, but I'll give it my best guess. To try to point you in the right direction. First, you need to know the torque of this magnet. 1 horse power 0.74569 kilowatts So to get a 1 kilowatts, you need 1.35962 horsepower. The motor will have a certain efficiency. I do not know if this is factored in to the motors power rating, however if the efficiency is, say, 90%. Then you will need to divide the horse power by 0.9 to get the correct horse power rating. Is this a motor part of a diesel / fuel generator, or is it part of a wind turbine / water turbine?
