totalPressure boundary :Performance Curve (constant RPM)

i'm now working on simulation to generate a performance curve of a radial blower ( to be compared with the curve from manufacturer- see attachment) using simplefoam mrf (OF 2.2.0)
for the first simulation which i want to achieve maximum flow rate ( static pressure difference of inlet and outlet = 0) i used this totalPressure condition for both inlet and outlet (duct):
type totalPressure; rho none; psi none; phi phi; gamma 0; p0 uniform 0; value uniform 0;
for the next simulation i would like to increase the static pressure difference to 50 pascal. Which one from below initial condition for outlet is the right condition to be made?
0/p for Outlet
type totalPressure; rho none; psi none; phi phi; gamma 0; p0 uniform 50;
type totalPressure; rho none; psi none; phi phi; gamma 0; p0 uniform 50; value uniform 50;
type totalPressure; rho none; psi none; phi phi; gamma 0; p0 uniform 50; value uniform 0;
I tend to use totalpressure since i can set the static pressure hence easier for me to obtain the static pressure difference without need to do extra calculation etc.
please correct me if i did wrong.
thank you in advance
