We have a project for school where we have to build a solarboat. I have been given the task of designing a propeller. But if I have to believe...
Yes, I'm trying to desing a propeller. And I'm trying to figure out how to calculate the pitch over the lenght of a blade. Because I coundn't find...
I've found a document on the internet where they show how to determine the pitch along the lenght. But is this the right way to do it? D = radius...
So correct me if I am wrong. But I have a diameter of 7.5 inch. The Disc area would be (pi/4)*7.5^2 = 44.18 square inches. The expanded area of...
Well..... After a whole day of reading and thinking, I still can't figure it out. I don't know how find out what the expanded area (Ae) is. How...
Hello, To calculate the PSI (formula 5-7 from the propeller handbook) i have to get the Ad. And to get the Ad (formula 4-7) i need the MWR. But...
Thanks!

Yes, i have a standard B serie.
hello I am using the book of Dave Gerr to calculate a prop. But it is hard to read the diagram because i have a low Bp value (4,613). it's hard...
And then another question. In many formulas they ask for the diameter (D). But is this the maximum diameter that the propeller can be?
I am now reading the book that you recommend to me. but I still have a question, how do I find out what the velocity of water is.
