<HTML>Hi,
We are rebuilding a 1923 740 rodster and I was woundering if anyone has tried installing an oil sperator on the condensate side befor it enters the condensor? If so what did you use and how did it work?
Does anyone know what pressure the condensate side runs at?

<HTML>I wrote a paper on the subject. See "Papers" page of "Northeast" pages on SACA web site.
As for exhaust pressures, I have a gauge as a hood orniment on my condensor. In normal driving, no measurable pressure. Going fast up steep hills, 5-7 psi., maybe 10 psi maximum. If you build for 15 psi., no problem.</HTML>

<HTML>Thanks Dave,
Not sure of the web site you mentioned do you have a web address for it?
I think we have talked in the past, when this project got started.
Since then we have had a new boiler made, the car is a rolling chassis.
The body guy is starting to referb the body. Myself and some other guys are working on the piping. Lots of valves and devices were sorting trought them all now and tring to find there home.
All the valves have been rebuilt by me and later I will have questions about adjusting some of the regulators. Steam devices will be calibrated by a certified shop near by. If you have any info or experience with setting any of the fuel regulators or etc. I would love to hear about it.

<HTML>D.M.,
Back in March of this year their was a discussion thread on Oil Seperators started by Peter Heid and believe he has written a very extensive paper on it that JW will shortly be putting on the "papers" link. To view the old oil seperator thread you will have to keep clicking back on older messages until you get in the March 02 vicinity. So much info on this website!
Best, George</HTML>

Has anyone seen the "papers" on this?
I have checked the sight over the past few days and haven't seen anything. I am interested in this if anyone knows how I can get a copy or get in touch with Peter please let me know.
Thanks

<HTML>D.Morgan,
Peter's Oil Separator paper is quite a substantial work -, unfortunately John has not yet had the time to put it on this website under "papers". Should be soon as John has almost completed the reclaimation of the entire website(after its total loss) and finding a new place to live. Hope it is soon.

<HTML>Hi George,
Thanks for the update.
In the process of assembling the car and was thinking of building a seprator. I hope the paper is up soon.
Thanks for your help

I am sure John Woodson is working to get the paper on his web site as soon as he can. He is very busy with a back log of work, as George mentioned he had a bad computer failure and had to move to a new home. Somehow he managed to keep the web site up and keep the forum going during his troubles. Because of his help, I would like to see the paper on John's site before it gets spread around but if he can't get my paper on soon, I will email you a copy.
Stay tuned

<HTML>Got one behind the rocker panel on the pass side, three chambers, filled with stainless scrubby pads. Steam has to zigzag through, has three drains which will drip for DAYS. Also have an IC care radiator cap installed on it acts as a vacuum break and as a pressure relief valve, using a 13 psi cap RP</HTML>

<HTML>Hi Peter thank's for the paper.
I've finally read it right through and it is an excellent gathering of information.
My understanding of centipetal vs. centrifugal always tripped me up so I've been through the section on centrifugal seperators several times and I believe there is an error on Pg 10 bottom paragraph. "The centifugal force increases proportinately with a decrease in rotational radius"
I think this is incorrect and should be "increases with an increase in rotational diameter".
The example in Figure 7 Pg 10 appears to show this but this is because by holding the periferal speed constant (1000ft/min) in fact rpm for the 2 ft diameter drops to 159.1rpm compared to 318.3rpm for the 1 ft diameter.
Using the Figure 7 examples but using rpm and the same diameters in equation 2 Pg8 the increase in separating force due to doubling in diameter is obscured by the halving of rpm which is a squared term.
Sort of times 2 then divide by 4?
I hope my reasoning makes sense. If you want to email me direct (pav@xtra.co.nz) I can send you the excell sheet I had to put together to get my head round this.
Cheers

<HTML>Mark, your reasoning assumes fixed angular velocity: for a fixed number of revolutions/second the force is proportional to radius. For a fixed number of feet/second, the force is inversly proportional to radius. (I think)</HTML>

<HTML>Thanks David
Yes I see now the sentence in Peter's paper infers this. ie "The centifugal force increases proportinately with a decrease in rotational radius (if the peripheral speed is unchanged) and increases by the square of the velocity"
Got it!

<HTML>Thanx Dave,
You are following my line of thinking which I believe to be correct.
Ron,
I guess I could have been more clear on that one. I really mentioned centripetal force to prevent confusion with centrifugal force as the terms are often improperly used. I may be in error on many points as it is hard to find a proof reader that can edit that type of content but most of the information is confirmed by multiple references. There is at least one genuine mistake in there, see if you can find it. It will be corrected on the HTML version and may go unnoticed.
