**Mass Flow Rate and Average Velocity Concept** In fluid dynamics, the mass flow rate is an important concept that relates the mass of fluid passing through a cross-sectional area per unit time. It is typically expressed with the equation: \[ \dot{m} = \rho A V \] Where: - \(\dot{m}\) is the mass flow rate. - \(\rho\) (rho) is the fluid density. - \(A\) is the cross-sectional area through which the fluid flows. - \(V\) is the average velocity of the fluid. **Question:** If the mass flow rate can be expressed as \(\dot{m} = \rho A V\), then the averaged velocity \(V\) should be _______ - **A. perpendicular to \(A\)** - **B. parallel to \(A\)** - **C. the direction doesn’t matter** No graphs or diagrams are included. This question focuses on the orientation of the velocity vector in relation to the cross-sectional area.
