    Thrust bearing pumping action

    I need to estimate the oil pumping effect a plain thrust bearing has due to rotational speed. Then make a qualitative comparison to a similar bearing. Both bearings use the same thrust collars on the active and inactive sides but the babbit surfaces are slightly different. Any help...

    Ideal radius for a bellmouth inlet

    Thanks for the insight. The device is actually a flow meter and I plan to increase the bore size to get more flow. The flow meter is about 4" long and opens up into a plenum. I was thinking of a radius say about 1/2D. Regards

    Ideal radius for a bellmouth inlet

    Surely this is basic, I want to calculate the ideal bellmouth radius (and lenght?) for a 2" opening where the flow rate is about 900 cfm of air (assumed 28" H2O presure drop). Thanks in advance,
