We are working on equal percentage valve plug design.We need to take static pressure at both inlet and outlet for inherent characteristics.But standard ansys material shows that results obtained by taking static pressure at both inlet and out are not reliable.Is it true?

Is the flow compressible ?
Do you know the mass flow rate ?

It is liquid helium at 4k temp. and i have taken the mass flow rate 1kg sec^-1 for 50mm valve so the flow must be incompressible.
