We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Dear Rob!

     Thank you for you reply!I have a long pipe containing compressed air, the air is modeled as an ideal gas model, if the pressure loss is large, the density change will be large and the corresponding velocity change will be large. I know the relationship between mass and pressure loss, but not the relationship between velocity and pressure loss.
