Question:

Fluid is accelerated as it passes through the slipstream of a propeller, Figure P11.10. Show that the average velocity of the fluid as it passes the plane of the propeller blades is the average of the upstream and downstream velocities, $v_{1}$ and $v_{4}$. Assume $P_{1}=P_{4}, v_{2}=v_{3}$, and neglect viscous effects.
