At this interval of 5 days, please do not tell me that you did not find any explanation on the Web. By the way, I refused to build one
LMGFY query since it would be too obvious, and if you considered the above reply did not meet your expectations, maybe you should ask yourself if your short
question was sufficiently well elaborated.
I want to know the equation for continuity for a compressible fluid
By the way, the video do has some relation with the continuity equation, both explains the same fluid transport phenomen. Have a look and exaplains why do you not agree, instead to say the opposite.

Anyway, you are right in the sense that it refers to uncompressible fluids, since density factor is treated as constant, as well as it is partially related, not entirelly related; now making another quick google search we can find this link:

This is a more general form, not only for physics, but also for chemicals, since it takes into account mass creation and destruction; Let`s know if this answer your question...
