APFIVE Incompressibility of Ideal Fluids
A student claims that when an ideal fluid flows through a constricted section of pipe, its density must increase to maintain the same mass flow rate. Which of the following best evaluates this claim?
A
The claim is incorrect; density decreases in constrictions
B
The claim is correct; mass conservation requires it
C
The claim is correct; density must increase with pressure
D
The claim is incorrect; ideal fluids are incompressible
