    Well yes there will be a hydrostatic pressure increase but its not unreasonable to start with assuming a consistent flow rate across all. Is the change in height so significant that the pressure difference will be considerable?

    I believe in this case the discharge coefficient has to be determined via testing. There are published values for this coefficient based on the orifice type and the reference I typically use is table 8-2 in the latest edition of Sutton's Rocket Propulsion Elements. It highlights several liquid...
