Here I have represented the Mach Number.

I am working trying Mass-Flow Inlet - Pressure Outlet and Pressure Inlet - Pressure Outlet, but in both cases, the results tend to overestimate my experimental curve of pressure loss - flow rate at high flow rates.

Since the tank outlet pipe reaches the open air, I'm imposing Gauge Pressure of 0 Pa at the Outlet and 101325 Pa as Operating Pressure.
Also I'm using Intensity [5%] and Hydraulic Diameter method at the boundaries.
