    The document contains information about orifice plate dimensioning for three water systems: 1. A 30 bar shower water system with a flow target of 17 l/s at 300 mWC inlet pressure. The calculated flow through the orifice plate is 1.565 l/s. 2. A sealing water system with a flow target of 1 l/s at 100 mWC inlet pressure. The calculated flow is 0.548 l/s. 3. A 10 bar shower water system with a flow target of 20 l/s at 100 mWC inlet pressure. The calculated flow is 1.534 l/s.
