I'm interested in the process.
The motor in question is for the sink on a motor home.
I'm not interested in using the manufacture's recommendation.

I'd like to determine the psi of a pump. All that is listed in the specs is the Horsepower, the Capacity (GPH), and the discharge head (in feet).

Is there some way to calculate the psi based on this info?

Thank you!

that works but there is no lightbulb meaning that there would be light if there were a lightbulb ... anyways, do you still waste electricity by just having the light switch on?

Imagine that I have an AC to DC (220V AC to 18.5V DC) Adapter for an electronic appliance and if the AC side is connected to the power socket and if the DC side of the adapter is not connected to the appliance will there be a significant voltage drop across the transformer & resistors of the Rectifier Circuit?? If I have the habit of doing this daily will it reflect in my Electricity Bill??

Thanks in Advance.

I am at university in Britain, and have the opportunity to learn some German for free. As an engineering student, I have a very tight timetable as it is.

How widely is German spoken as a first or buisiness language, and is there another foreign language that would be more appropriate for an engineer to speak?

I was just wondering...since they do deal with electrons, are they thought any physics concepts or even formulae in "electrician school" or whatever they are called?
And I know there is a big difference between an electrician and an electrical engineer, but can someone sum up the differences so I can have a clearer idea?
