This bent, flat tube is located on a horizontal plane and ideal fluid is flowing through it, as shown by the arrows.
According to me, pressure at 2 would be higher than pressure at 1. I think so because, for the flow to be sustained as it is depicted, velocity at 1 should be higher since the fluid there would have to cover a larger distance than it has to in 2. So, from Bernoulli's theorem, since heights are same, pressure should be larger at 2.
But my book says just the opposite. But if $v_1$ is lower than $v_2$, the flow wouldn't be straight as depicted in the picture. I'd preferably go with the book's answer but I also want to know WHY that is the case.
