Thanks Berkman :) I don't think I will start a fire or electrocute myself : ) and hopefully I don't let the smoke out of anything! I just want to make sure I can match the load of my heater with the output of the ZVS driver from eBay reasonably well..

Thanks for the reply. I've googled quite a bit of stuff,, but I am a mechanical guy in the electrical world and sometimes feel a bit lost :)

Hi folks, I want to build a heater similar to this http://www.thermon.com/us/products.aspx?prodid=10 , using a ZVS power supply from ebay (such as this one -http://www.ebay.com/itm/381569526996?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) ) As well I would like to replace...

Just thought I would bump this.

Id like to just try a proof of concept prototype - maybe using some pipes 1" and .625 OD? with 0.125" wall? and perhaps 6" long? The temperature I am looking for is around 300F. - for the initial test, It will just be in air, so I would suspect 300 ish watts should apply some significant...

Thanks for the reply, what I was thinking of is using something similar to this, but with 2 pipes - you can double the wattage (using transformer oil or something inside to conduct the heat from the inside to the outside. The below link is using a copper (non mag) conductor on the inside, and...

Hi Everyone, I am a mechanical Engineer, playing in the electrical word :) I was thinking about creating an inductive heater, that was based on 2 concentric pipes, with a current flow path that is from the inside pipe, through to the outside pipe, and utilizing an induction power supply to...

Hi Folks, It seems there are some differing opinions in my office with respect to the following. If one is to pump water through a long lenth of 1.75" pipe (16000'), how would you go about predicting the temp rise of the water as it flows along the pipe? From what we have found, when...

Hi, The cable is parallel to the pipe, here is a sketch of what's going on. We have the ability to pump at very high pressures/rates (upwards of 10k PSI)

Thanks for the quick reply, We are not so concerned of the pressure drop across the anulus, what we need is to determine how hard we will have to pump in the annulus, to apply some force (f) to the wire inside. What we are trying to do, is lift a wire (without) direct mechanical contact...

Hi Folks, How would one go about calculating the drag force that would be applied to a wire (or in our case a small (0.130") fiber optic cable, that is inside of a small diameter pipe (.56")? I've tried several methods, but none seem to match what we actually measure when experimenting. We...
