If the continuity equation is applicable, what will happen to the air density (rho) if the cross sectional area of a tube changes? (low speed, subsonic and incompressible flow)
Domanda 6, Principles of Flight - ATPL - Airline Transport Pilot license
Rho1 < rho2
Rho1 > rho2
Rho1 = rho2
The density depends on the change of the tube area
