I really want to understand your conclusion. Maybe the different notation confused you, because is a really simple math.
I gonna use "." for multiplication and "," for decimal mark. ok...
No... almost this.
In this book Henry P.G. Darcy and other pioneers in hydraulics, (you can find in google books)page 29/30/31 Darcy propose an experimental equation:
R.I=a.v+b.v²
That que be expressed by:
R.I=b.v²
b=a+b/r
For Cast Irons
a=0,000507
b=0,00000647
so...
I've been reading a book about compressed air and i saw a equation for pressure drop that i can't find your origin:
Hf=(2/d).l.?.?.v²
Hf= Pressure Drop (kgf/m³)
d= Diameter (m)
l= Lenght (m)
?= Specific Weight (kgf/m³)
?= Coefficient given by (0,000507)+(0,00001294/d)
v= Velocity (m/s)
Can...
i've been trying to design a seal pump data sheet but i dont know how to develope this calculations. There is a single pump to seal 4 areas. How should i proceed to design this pump?
