the angle of my prop is 15 degrees..how about the tip speed ratio TSR?..does it the same with ur formula?..i found this on the internet.. RPM = (60*V*TSR)/(pi*D)..

@Gabe21: the angle of prop in ur example is with respect to the plane of rotation?..why is it that it is divided by 90?..

thanks for the reply..it really helped me a lot...do you have some basis or references about the calculations?...does the analysis of the propeller in air same as that when it is in water?...does the density of water affect the rpm of the prop?...

hi to all! Say i have a uniform flow of water of 1m/s.. if i put a propeller with known diameter and blade angle...what would be its RPM?...i want to design a flow meter...pls help me!..i need to have basic and approximate formulas on the blade parameters and its RPM..thanks! Regards dioross

thank for the reply.. Do you have some ideas about basic calculations?..:)

hi everyone! need some help about propellers..say i have a fixed mounted propeller and a flow of water with known velocity runs through it.. what would be the rpm of the propeller??.. i know there a re lots of things and parameters to consider... i need some good references, calculations ,and...

im having a special project in flow meters and i want to design a propeller that provides RPM given a velocity of incoming water.. so i can disregard power, lift,drag,torque calculations..or what should i do?...all i want to have is the parameters of the propeller that provides the designed...

thanks for the reply :)..do you have an idea on the blade design?..or just a simple design?..

hi!... Does anyone know the relationship (i mean formulas) relating to the incoming air velocity to the rpm of a wind turbine?..i need to have a design in the generator part and also the parameters of the propeller..thanks! best regards, :)
