WebApr 4, 2015 · For typical sub-sonic, open pipe flares, headers are designed for 0.5 Mach or less. The 0.7 Mach figure applies for PSV tailpipes. You have considered relieving pressure equal to the header pressure, which resulted in a small-size line. In reality, the header pressure will be closer to 10-15 psig, not 1000+ psig. WebFor Mach = 0.2, the flare diameter is calculated as follows: 6.9.3 Calculation of flame length The heat liberated, φ, in kilowatts, is calculated as follows: From Figure 6.6, the flame length, Lf, is 52 m. 6.9.4 Calculation of flame distortion caused by wind velocity The vapor flow rate is determined as follows: WebJul 25, 2013 · Start with a outlet line size as recommended in API 526 based on the orifice area required, the mach number for outlet line size should be kept below 0.7. You need to increase the line size if the mach number is greater than 0.7. Hope you understood.
