How about Cold Fussion? Cold Fussion is a method of generating electricity from sea water. A lot more complex, but the D20 which is the...
Paul, the salted grapefruit experiment that I'm familiar with puts an iron nail and a piece of copper in the grapefruit. the grapefruit provides...
Leo, It seems clear to me that most everyone prefers a formula (model) which relates identifiable physical parameters and/or properties. We...
According to Alberty & Daniels, Phyiscal Chemistry text book, 5th edition p. 572. Table 18.1 Viscosity of water in (Pa s) or ( Kg / m sec)....
Thanks Eric. Very good stuff. ~ Michael
The lines look nice. What material will you use? The transverse metacentric height looks a little low to me, but perhaps someone more...
I’ve been following this thread with great interest. I have not finished reading all the papers which you have given reference to in this thread,...
Form Drag In regards to Form drag, I noticed that the first cause is attributed to the hull geometry while, while the second two causes are...
Thanks Fanie
Fanie, What is the basis for this conclusion about speed and power input? Did you build a model, or is this some simulation, or else?
More Cones In the case of your current Sheer curve, because it lies in a plane, then yes it would be the intersection of a cone with a plane....
Rick, You have a nice illistration for the set of sheer curves that fit in a plane. Similarly, i think there is a more general set of sheer...
Large diameter rope made of natural fiber.
Rick that is a nice presentation of the idea.
Droussel, I can second many of the things which have already been said. Spend considerable time analyzing other designs. I think Bolger's boats...
Seems Dreamer is going for a sheer which is close to a planar curve, i.e. it lies in the same two dimensional spaces. I think it is true that...
I have read more than one designer discuss how sheer curves must be compatible in both the profile and the plan view for them to look right in 3D....
Gonzo, Thanks for that tip. I'll have to try it. Joe, hang it from a level, then use a ruler to measure the low point. Dreamer, I...
Cp for SLR 2.4 Eric, Thank you for your thoughtful response. ( deleted that question because it is closely related to a quesiton Eric has...
Cp vs Speed/length ratio This graph might be helpful. The data that Eric supplied us for Speed/length ratios correlated to optimum Cp values...
