Sorry i'm not being specific enough I guess. I need to be able to measure multiple voltage measurements. I guess a DMM measuring a single voltage at a time would work if it was cheaper to buy that and an electronic switch, which using a computers parallel port can switch between up to five...
Hello all,
I am looking for a digital voltmeter that can either connect to a computer directly or converts the voltage into a digital signal, which I can put through to a computer. I am looking for a cheap device that runs continuously refreshling at a rate of at least 3-4 times per second, the...
Thank you Patricia, the thing is we work with hydrolics and hydrolic motors and ussually don't work with heat transfer, but one of our recent projects requires the working fluid to be maintained at a certain temperature (to limit bacteria growth in the water). So that is why I was having such a...
Thanks a lot guys, I really appreciate the help. Yeah, the formulas are simple enough, I'm just having a hard time determining the convection heat transfer coefficients for water and air. I realize its based on the flow and temperature of the fluids but I can't find a chart or graph that has...
It might sound like a homework problem but this is my frist problem at my first engineering job. They have given me the flows and volume in imperial because we are working with an american customer but we are a canadian company so temp is in celsius.
Forgot to mention that the flow is...
I'm working on a heat exchanger at work. The following is what I have been given:
-Both cooling fluid and working fluid are water.
-working fluid must stay between 20 to 25 Celsius
-Cooling fluid is max of 15 celsius.
-heat exchanger is single plate, stainless steel 22 gage.
-Working water...
