Why wouldn't you define them as equation goals?
Or are you asking what the equations are?
Or are you asking how to create a graph that shows a parameter under multiple conditions? This is straight forward, use parameter studies. Someone asked this recently, you may want to check recent posts for pumps...etc for more details on the process. But basically you setup the problem and have flow simulation run through all the iterations then you can build your graph. Or clone the study, make the changes yourself and then output the data and make your graph.
Thank you for your replay,and that is very usefull to use parameter study,but I am realy asking what the equation is? and what is related to!!
who's asking you for the parameters?
do you have definitions of what those parameters are?
I found this equasion :
h = (p2 - p1)/(ρ g) + v22/(2 g)
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?
looks like it could be used to compare designs
