True OR False ?
A Newtonian fluid is, by definition, also incompressible. The speed of sound through a fluid is always constant for that fluid and not a function of anything. An incompressible fluid is treated as having a constant density. + An incompressible fluid is treated as having a constant pressure. 5. The conservation of mass equation is only applicable to steady state processes.
