Jon,
I had seen the Bernoulli graphic before but, the efunda site is a nice find, I will bookmark this when I get home..thank you! The calculator is quite neat.
If I may return the favor, here is my base reference on the machine shop end. http://www.jjjtrain.com/vms/library.html
a link I followed from a previous discussion regarding an online machining source.

Subject: Re: [PSUBS-MAILIST] Venturi vs Kort Nozzle?Hi George,
With your ROV experience, the issue of increasing available thrust is not new to you of course.
To my knowledge, the only difference here is the foil section on the kort nozzle would be harder to replicate for a homebuilder than say a simple constriction...(venturi). To get that foil section on a kort perfect and even all the way around x 2 or 3 thrusters...is a bit of a challenge from a construction standpoint.
Obviously, the Kort is the preferred method (numbers used in the field) but, I found it interesting to see a simple venturi on a well known commercial submersible. It just makes for an interesting simple option to look at.
Yea, ...you've'e just got to smile at HURL!
