Drexl and GjFi Thanks....This is what I was looking for. I have not worked with this stuff for 30 years so I needed a little jump start. I know it seems odd to try and do it this way but I have a very small and limited box (regulations) to work within to get heat generated. Thanks again

Has anyone had experience with generating heat (to heat a fluid to 240 F) by using pressure drop through an orifice plate? I want to heat hydraulic oil from 70F to 240F without using electric heaters, just pressure drop through a nozzle or an orifice. Any help with general formulas would be...

Does anyone have experience with Pall Disc Tube membranes for seawater desalination applications? I am looking for new technologies with regards to small desal system (upto 10000 GPD)design. The goal (as always) is trying to reduce operting and maintenance costs. What about energy recovery...

Thanks for replying Greg. My defination of jacking would be, through lateral force inputs at the contact patch, raising or lowering the sprung mass and increasing or decreasing the vertical force at the contact patch. I am interested in the jacking forces produced by lateral force inputs when...

I am researching (trying to understand) jacking forces produced by SLA suspension systems. I think that jacking forces can be produced by both elastic (through the springs)and geometric (through the linkages) lateral force inputs. Can anyone help me plow through this stuff. Any help is most...

No. Excel only plots 2D graphs. I found some shareware on downlods.com that did the job. Good luck.

I need some assistance specifing a pump type (impeller, PD, screw, lope, etc) that will perform to these specifications: 600 GPM Head 400 ft Suction 10 ft This will be pumping deisel, gasoline, and jet fuel. It is a transfer pump system. My project is to integrate an "off the shelf" pump into...

Can anyone provide the basic calculations for converting Cd and Cl in real force numbers. I have volumns of tunnel data in coefficient form and I need to convert it to force numbers so the end user can understand it. Thanks

Does anyone have info and/or links to available K&C rigs available to test on in North America? Any info their operation, data output, how to use them, what can be learned or a test plan will be appreciated.

When did Chuck Hallum pass on. I was in a seminar with him 10 months ago and was corrosponding with him via e-mail earlier this year. He seemed OK. Does anyone have any info???

hpfreak Thanks for the reply. Sounds like you and I may be in the same business. Would not horizontal movement towards the outer wheel reduce the lever arm length from the roll axis to the outer contact patch. This would increase the loading to the outer wheel and increase roll. Belief in my...

Any thoughts on roll center position and migration during a roll/dive event. I am working with a non-parallel 4 link suspension typically found on front engined, rear wheel drive US autos. I would think that the front roll center position should stay as "calm" (centered) as possible...

Greg Thanks for the input. I know it is impossible to get tire data from the mfg's so I spend alot of time collecting vehicle performance data and trying to make sense of it. You confirm what I have found-a small increase in air pressure (1 to 2 psi)increased lateral grip (approx 0.1 G) and...

Does anyone have any input on the physics of tire grip and what is really happening at the contact patch (CP)? I have read Chuck Hullman's SAE paper and his theory of delayed localized heating at the contact patch. How does CP area relate to overall laterial grip since friction is the normal...
