Problem Statement: When using the compressible gas pipe unit operation with the "compressible gas" method, the mass density reported on the Performance tab > View Profile is incorrect. If we change the method to "perfect gas", the mass density gives a correct value. Why is that? | Solution: This happens due to the flash calculation of the inlet stream. The "perfect gas" method always uses the ideal gas equation for density, so the calculation is not affected by the flash result of the inlet stream. On the other hand, the "compressible gas" method uses the flash results of the inlet pipe to calcu... |
Problem Statement: The tube pitch is highlighted in red when I opened a file in V9.0, but it didn't show the red colour in V8.8. | Solution: When longitudinal fin tubes are used, the default tube pitch is 1.25*(TubeOD + 2*Longitudinal fin height).
V9.0 shows the correct calculation.
Keywords: tube pitch, longitudinal fin tubes
