Default Velocity inlet calculated from Mass Flow Rate

Hi everybody, I'm modelling a Hot Water Tank with a Mass Flow rate inlet of 0.0972 kg/s with an inlet diameter of 15mm. When I initialize the simulation computed from inlet, I have an X velocity of 0.00652 m/s while I'm supposed to have 0.55 m/s from hand calculation. What's wrong??

Thanks for your help

Anthony

Hi Anthony, I am guessing the units for your grid are not right. Go to Grid--> Scale and make sure that you scale the grid by the correct factor to bring it to SI units. I cannot think of any other reason!
