Fluid mechanics

Ideal fluid flows along a flat tube of constant cross-section, located in a horizontal plane and bent as shown( in figure is the top view ) . The flow is steady. Are the pressures and velocities of the fluid equal at points 1 and 2 ? what is the shape of streamlines ??

please help me

The fluid particles when bending round the corner need some centripetal acceleration towards the center of curvature. In this case the force on the particles need to towards the center which would lie roughly on the line going from 1 to 2 and extended. Accordingly on a fluid particle somewhere between 1 and 2 a net force in the direction from 1 to 2 must act. This means that the pressure at 1 must be greater than that at 2 and accordingly the velocity at 2 must be greater than that at 1.

SIR I HAVE A DOUBT

AS : A*v=CONSTANT SHUDNT THE VELOCITY BE CON STANT

The area of crossection has changed at the bent.Hence,the velocity
