Lab 2 (I) 2

1. The document describes a valve (VLV-100) with its connections, parameters, sizing conditions, and stream properties for an inlet and outlet stream. 2. Key specifications of the valve include a pressure drop of 280 kPa, 50% valve opening, ANSI/ISA sizing method, and a sized coefficient of 5.168e+004. 3. The inlet stream has a temperature of 143.6°C and pressure of 1200 kPa, while the outlet stream has a temperature of 140.4°C and pressure of 920 kPa.
