Oh, right! Thank you! I have a follow up question tho: Why is it that for the density change relative to the total densitiy an error of (or under) 5% is good enough to be considered incompressible, whereas for the perecent change in density an error of 10% is considered OK? I know that its just...
Hi guys,
I'm trying to delve into compressible flow and in the various textbooks I'm reading I've found two school of thoughts when it comes to how to calculate the threshold (or error compared to incompressible flow) of 'M' when to consider a flow compressible.
