The issue of fluid flow velocity in pipelines

2009-04-16View Original

Thread Content

While flipping through some books today, I came across the recommended flow rates for various media, and I’m a bit confused about this. I hope everyone can give me some advice: 1. Why is it that the higher the pressure in an oxygen pipeline, the lower the recommended flow rate within that pipeline? 2. The recommended flow rate for ammonia increases gradually at low pressures, but when the pressure exceeds 20 kilograms, the recommended flow rate drops significantly to 3–8 m/s As I understand it, the higher the pressure, the higher the flow rate that should be allowed! I hope everyone can explain it to me! Ah! !
