Digital Feature: Relief valve sizing for two-phase flow
WebJan 26, 2024 · Based on the relief load, an orifice is determined—it is advisable to then check for two-phase flow. For this article, a two-phase sizing is considered. The vessel in this example is 6 ft in diameter and 16 ft T/T length with ellipsoidal heads. The standard heat absorption equation (as described in API 521) is used to calculate the vapor ... WebComponent 4, Reference number: ISOLATE 5167-4:2003 Orifice and venturi pipe flow meter are described furthermore calculations for liquid flow and gas flow are shown with product. WLTM 5167 equations forward the orifice distance and for calculating pipe flow rate with gas flow or with liquid flow are showcase and used in example calculations. WebFlow calculation principles. The principles of flow calculations are illustrated by the common orifice flow meter (see Figure 1). We need to know only the size and shape of the orifice, the diameter of the pipe and the fluid density. With that information, we can calculate the flow rate for any value of pressure drop across the orifice (the ... ct0042o
