Following the tutorial example, but the pressure drop didn't increase/decrease significantly (only 1 unit or less ) with the increase/decrease inlet velocity (0.01/0.1m/s). I know that the pressure is divided by rho, with a unit of m2/s2.
Could anyone give me idea why this happens?
My model is a cylinder of 0.1m diameter and 0.3m height, with p=10e5 at outlet and u0.02m/s at inlet, to look for a relationship of pressure drop vs. velocity by changing the inlet velocity. for postprocessing, the paraview is employed with an 'integration variable' function to extract the pressure and velocity at the boundaries.
Thanks in advance.
