i need to compute the area of a parcel of lot and use a suitable program so i do not compute manually so I can print the results easily. This is a surveying program which can generate results even for several lots. If I cannot download a free program can you inform me of what program should I look or purchase.

I'm going to be doing some experimenting with a small portable ultrasonic welder I am purchasing from asia. I understand that it probably won't comply with local standards so I am going to get an electrical engineer to look over it, to see if its safe to use. However my main concern is the output to the transducer. I've been told that ultrasonic welders can run as high as 3000volts through the output. I am worried that because of this high voltage, it may be dangerous for me to handhold the transducer. I understand that this is a question that I should also put to the engineer and I will ask this. In the short term however, I was wondering if anyone would be able to tell me approximately at what power level/ voltage combination, electricity becomes dangerous?

I have a standard transformer with 7 wires:
2 black
2 red
2 yellow
1 red/yellow striped

What connections do these wires correspond to?
That is, which should connect internally to the primary coil, the secondary coil, and coil-taps (based on the number of wires, I assume that the secondary coil is tapped).

I must determine this in order to connect the wires (externally) appropriately.

Any help is greatly appreciated!

power factor is the loss factor by the consumers . install a 100 kva transformer and power factor is 0.5 so power utilised is only 50 KW. i.e due to consumer the power selling is losing . so why not KVA meter?

wow, I did not think so many people would
try to dissect the components.

forget, in this case, that the vehicle is
a train.

let's move the weight to the water and
make it a freight cargo ship.

the ship has a diesel engine, it also
has photo electric cells plastered all over it
and it has 6 monster sails.

ugly as sin ship. ok.

with just the sails, the ship will SAIL along
at 2 kilometers an hour in speed.

if we remove the sails and just have
the photo electric power, the ship will
travel at 4 kilometers per hour in speed.

if we remove the photo electric cells and
instead, install diesel engines, we can
travel 16 kilometers per hour speed.

in some situations in power, it is a good
idea to combine power resources.

the question then, is, if we were to combine
all 3; diesel engines, and
add the photo electric cells and
add the sails, would the ship only go
16 kilometers per hour speed--or would it go faster with the other two sources also working
concurrently?

I'm a bit confused with the concept of electricity, and hopefully someone could clear my mind.

If a Utility Company has a capacity of 1 mW, what does it mean? Does it mean that it creates 1 mW per second? if so, does it mean it creates 9,600 mW-h?

My brother is a senior in high school, and he is interested in doing a 7 year PhD program for electrical/computer engineering. This would make him roughly 25 years old by the time he finished. I told him that the PhD at such a young age may over qualify him for certain jobs at smaller companies. For instance, if a P.E. had a 10 man business built on a bachelors degree, would the thought of hiring a young PhD not be slightly unappealing? He says, that he will do research at a place like AMD or Intel. Would his age and lack of experience conflict with is level of education?? It just seems like those jobs would be difficult to get, and would be reserved for people of more seniority. Is his best shot teaching at the collegiate level....unfortunately he doesn't want to do that. What do you think?
