SUMMARY
The discussion focuses on calculating the nitrogen purge velocity in fixed volume tanks, specifically addressing a scenario involving four tanks with a volume of 90m³ each, initially at 701.3 kPag and purged to 131.3 kPag through a 100mm pipe. Key factors influencing the velocity include not only the pressure and density of the nitrogen gas but also the pipe's length, roughness, and entry geometry. The conversation emphasizes the importance of considering both major and minor head losses in compressible fluids, as well as the impact of temperature changes on flow measurements.
