I am doing analysis of centrifugal Pump which is supposed to develop suction head (Hs) = 7mtrs and Delivery Head (Hd) = 35mtrs with Mass Flow Rate (m) = 32.6kg/s.
1. I am giving Boundary conditions in Fluent as Inlet mass flow rate and Outlet Pressure. Now if I convert Hd to Outlet Pressure using Head = Pressure/(Density * g) then should i directly enter this pressure as gauge pressure in the outlet pressure BC? Since default Operating Pressure in Fluent is set as 10325 Pa. If not what am I doing wrong?
2. If I have to set Inlet Pressure BC do I need to Set it Negative, since the pump will be creating suction pressure?
