Just got back in the office... Gentlemen (and ladies as applicable), Thanks for all your input! Cockroach, it was scary reading your response. While out of the office I had our prototype shop start fab'g parts with virtually the same methodology / design as you describe. The valve will still...

Imagine, if you will... A valve which is typically actuated via vertical displacement (downward stroke)... However, I have managed a means to activate the valve via rotational motion. I was hoping to get a few ideas from the forum on how to translate the vertical motion (I have to deal with...

RWF7437, Thanks for your response... I work for a fluid delivery company in the plumbing industry and have already constructed a crude rig to begin gathering empirical data. I think your right...I may have to work this problem bass ackwards (get the empirical data than see if any...

Tremolo, Annular flow of water... I was going to equate the annular area to a pipe of respective size, however I have heard this leads to significant error; ie, an annular area of .091in^2 = a pipe of .17" R. The reality of the problem is I need to quantify the flow rate, and / or the...

Gentlemen, The piston - cyclinder was a bad analogy. Think only of the problem statement, do not assume this application is for an engine! I will re-phrase my question in a more rudimentary form...How does one calculate / predict annular flow given a fixed area, 35 psi and water. Let's just...

How does one compute the annular flow rate given the area? Assume 35 psi and water (@ room temp) as the fluid. Example: I have a piston within a cyclinder. The annular area between the piston and the cylinder is .091 in^2. Pressure is 35 psi. For ease of calculation consider this a static...

Make sure your feet are out of the way!!!

I type these responses with my left and right hand... Whoaaa... I must be Super Designer :~)

Biggadike and Viktor... What do you think R & D stands for??? Rip-off and Duplicate. It's unfortunate but when it comes to truly innovative design, most of what is out there tends to have it's roots in the forementioned play on the acronym. Ram air for instance?!

Come on guys, prior to doing any modeling, it's obvios you have to have some solid model visualized in your mind! I totally disagree with having to think spatially to be a good designer. More definition is required. You must think spatially to be a good Industrial Engineer, true. But to be a...

How can a venturi for air induction be optimized? I am inducing air into a closed vessel via water flowing circumferentially about a tube vented to atmosphere. The nature of the water flow creates a negative pressure (vacuum) and induces air into the closed volume (there is a one-way check valve...
