Using Inplant to calculate multi-stage pressure-reducing orifice plates

2010-02-01View Original

Thread Content

The medium flowing through the orifice plates is liquid water in a nearly saturated state; after passing through multiple stages of orifice plates, the pressure drops from 8.75 MPaG to around 1.6 MPaG. I’ve read that the purpose of using multiple orifice plates is to reduce the pressure drop at each stage and prevent cavitation. However, my supervisor told me that the water completely vaporizes after passing through the first orifice plate. When using Inplant for calculations, does it mean that the first orifice plate and those that follow need to be calculated separately? I hope experts can give some guidance! Thank you
