    Fluid Flow Problem-Viscous Flow

    Yes, I've come to realize that. I was trying to compensate for that problem by incorporating HL from friction, but that was incorrect. I'm now using the Poiseuille equation: \upsilon \pi R^2 = \frac{\pi R^4}{8\eta} (\frac{|\Delta P|}{\Delta x}) Any additional suggestions?

    Fluid Flow Problem-Viscous Flow

    The problem is not making it work. It flows quite well in this small tube, due to the high pressure gradient. I am simply trying to describe the process in a quantifiable way. I've been looking at the Stokes equation and Hagen–Poiseuille equation this morning. These seem to be the...

    Turbochargers, what's the diffrence between the turbine and compressor

    No. A turbine is designed to lower the energy of the air. A compressor increases it. They are designed for two different things and are not interchangeable. Just having a "curved blade" is meaningless. There are critical parameters associated with the twist of the blade, as well as with...

    Turbofan Spool RPM: Mathematical Relation for Performance

    You more than just RPM to quantify performance. Diameter of the fan, pressure ratio of the overall compression stages...

    Fluid Flow Problem-Viscous Flow

    I am working on a fluid mechanics problem modeling something I've come into contact with at work. I have an open to atmosphere reservoir of a fluid with properties as follows SG=1.48 Viscosity= 47000 Cp Height of fluid column, 3 inches or so. i.e. Neglible I then have a pressure...
