WebJul 23, 2024 · $\begingroup$ The higher speed over the curved path comes from the mass flow rates being the same. Just assume incompressible at first to get the intuition. Once the air stream splits, you have to get as much mass flow around the top as the bottom. So it has to go faster if that path is longer (longer if curved) because has to go further in ...
