    Pressure of stagnant fluid volume in rotating cylinders

    The liquid has a density of ~50 lb/ft^3 and viscosity of ~1.5 cs. The gap between the shaft and the housing is ~0.5 inch

    Pressure of stagnant fluid volume in rotating cylinders

    I have found some equations on page 111, §3-2.3 of "Viscous Fluid Flow", 2nd Ed. Following their methodology and using MathCad to cheat at the inegration! I am getting the pressure dropping off very quickly (and going negative) from the non-rotating OD (housing). The Reynolds numbers are very...

    Pressure of stagnant fluid volume in rotating cylinders

    Thank you Astronuc and Clausius2 for your responses. Since I am more of a nuts and bolts engineer can either of you point me to some equations for the 'simple' model (laminar flow) to solve for pressure over the radius? Thanks again.

    Pressure of stagnant fluid volume in rotating cylinders

    I have a high speed rotating shaft (~30,000 rpm). Outside the shaft I have a relatively stagnant volume of fluid surrounded by a non-rotating cylinder (housing). I am looking to find a 'simple' laminar flow model to describe the pressure of the fluid fat any point radially from the OD of the...
