Thanks for the explanation. Just to make sure we are on the same page. If I have a DC power supply that has a +12V terminal and a -12V terminal I could get either 12V or 24V depending how I connect things and if they are left floating. Then back to my situation if I leave the DC outputs on my...

I am still kind of new to all of this. Could you explain a little more. What do you mean by stack? Are you saying this only applies if there is more than 1 voltage source? The 24V transformer I am using does not have a ground connection on the output side only the input side (120V). Would this...

Sounds good. Thank you for the reply.

Yeah I should have said that but I was trying to cut down on typing. The hot lead for the 120 goes thru a switch then a fuse then to a terminal block then to the transformer. So I can connect the grounds together. Should I even bother with the diode inline with the 24V DC pump ground?

There is a 3 prong plug that plugs into a wall outlet. The cord then comes into my enclosure thru a cable gland. From there the live and neutral wires go to the input of my transformer. The ground wire goes to a terminal block. Then the ground wire also goes to the input of the transformer.

I have a questions about AC and DC components being grounded to the same spot. I have a power supply box that takes in 120V AC and brings that into a transformer that converts it to 24V DC. On the way into the box the ground wire from the 120V AC is brought into a grounding terminal block and...

Thanks for clearing that up the 1.8 F/C was where I was going wrong.

I was trying to convert a quantity in BTU/(ft*hr*F) to W/(m*C) and I can do it just fine by using a conversion factor from a table online, but what I want to know is how to come up with that conversion factor. The conversion factor I looked up and have been using is 1 BTU/(ft*hr*F) = 1.73...

Thanks

Anybody?

I need someone to tell me if I am approaching this in the right way. In my diagram I tried to show a section view of a wall of a pressure vessel with a cylindrical plug welded into a hole in that wall. I am trying find the stress on the welds in question. This is a small part of a larger project...

No worries. If this eqn does not totally apply what would be a more appropriate way to spproach this

I went on wikipedia and under Gay - Lussac's Law they had: P1/T1 = P2/T2 Which if you rearrange you would have P1T2 = P2T1

If you have a vessel that is rated for 500 psi at room temp how would you go about determining if it will fail if you do the following fill it half way with water then pressurize to 200 psi and heat to 100F i am trying to purchase a vessel for a project i am doing and i want to reassure...

In may I graduated with a Bachelors in EE. I have been working at my current job since then as an electrical engineer. I work for a smaller company and don't find the work i am doing interesting. Also from conversations with my friends who also graduated with me i think I would be happier at a...
