Cavitation in a pipe with incompressible fluid flow does not affect the conservation of volumetric flow rate, provided there is single-phase steady flow at both the inlet and outlet. The presence of cavitation may create vapor bubbles, but these do not alter the overall flow rate conservation principle. The volumetric flow rate remains constant as long as the flow conditions are maintained. Understanding this concept is crucial for fluid dynamics and engineering applications. Therefore, volumetric flow rate conservation holds true despite cavitation in the system.

Homework Statement


If you have a pipe where an incompressible fluid flows. What happens if we get cavitation - can we still say that the volumetric flow rate is "conserved" in the pipe?

Yes, as long at you have single phase steady flow of liquid at the inlet and outlet of the pipe.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
