Hello, I want solve pressure drop of orifice plate, but I can't set conditions well. When I solve tube DN10 of length ~340mm, orifice plate in the middle with hole diameter and length both 2mm with conus. Solidworks compute absurd pressure drop 18 MPa. Initial conditions: water, IN: inlet mass flow 0,113 kg/s (fully developed flow), OUT: static pressure 10 kPa. Please could you help me what I do wrong or how to solve real value of pressure drop step by step? Thank you in advance for your reply.@
