Question

A two-dimensional reducing bend has a linear velocity profile at section (1) . The flow is uniform at sections (2) and (3). The fluid is incompressible and the flow is steady. Find the maximum velocity, V1,max, at section (1).

Answer 1

As given in the problem statement,flow is in compressible and flow is internal flow

Re=5*10^5

Using equation

V=Re/density*diameter of pipe

Maximum velocity=98.98 m/s
