Dear friends
I made a flow study of the pump shown in the pic inserted
I defined the inlet and outlet as Environment Pressure and I also defined the Rotating Region of the impeller and I calculated the drop pressure and the Efficiency as goals of my project.
My question is : how can define THE HEAD PRESSURE RATE [M] and the GRAPH of (H,Q) Q=Volume flow rate?
Best Regards
I found this equasion :
h = (p2 - p1)/(ρ g) + v22/(2 g)
where
h = total head developed (m)
p2 = pressure at outlet (N/m2)
p1 = pressure at inlet (N/m2)
ρ = density (kg/m3)
g = acceleration of gravity (9.81) m/s2
v2 = velocity at the outlet (m/s)
I think this usefull for my study
what do you say?
