    LabView: BiSection Method

    Is there a function in LabView or a known subVI that can solve an equation for roots using the BiSection Method? For example, I have an equation: lambda*e**(lambda**2)*erf(lambda) - (Cp*(TL-TM))/(L*sqrt(pi))=0 where: erf(lambda), Cp, TL, TM, and L are known constant values that are designated...

    GC Calibration Standards Vendor

    Does anybody know of a couple of vendors that sells GC calibration standards or gas cylinders with reagents of suitable purity? The gases I am currently looking for are: 1. Hydrogen 2. Carbon Dioxide 3. Carbon Monoxide 4. Methane If possible, I'm looking for a QT cylinder size (US DOT Spec...

    Distillation Column Simulation Software

    I was wondering if there was any software out there that can help cut down the iterative process of the Fenske-Underwood-Gilliland equations/correlations to estimate the key parameters in a distillation coumn or possibly any other software that may be helpful in distillation design and simulation?

    Particle Size

    Ok, this is a stab in the dark. Does anybody know the typical droplet size of generic spray bottles or those pump sprays (like found in hair product stuff or perfume)? I'm trying to find something out there that could simulate in the 1-20 micron range, but something tells me a spray bottle's...

    Custom Mist Eliminators

    I currently am designing a gas-liquid separator and I'm trying to find a manufacturer that specializes in custom mist eliminators. Because my separator is very size constrained due to the application it will be used for, the dimensions for the separator are roughly 3.25" ID diameter and roughly...

    Vacuum Formed Ceramic Fiber Radiant Heater

    Ok, I have a question that I am hoping someone out there can answer. I am a fairly new engineer and I am in the process of using a VFCFRH (for short) in junction with a new catalyst to raise it up to 500 Deg. C. (Don't ask me why, because the reason keeps changing). Anywho.... I have an E...
