    misunderstood valve specifications.

    I'm examining a military specification for a servo valve assembly and there are a few requirements/specifications that don't make a whole lot of sense to me... The spec states that the "valve bias pressure at hydraulic null shall be 5 to 50% of supply pressure." The valve is a...

    fatigue in aluminum jig plate weldment

    what methods/design intent can be used to minimized fatigue with aluminum weldments? i'm working on a weldment with several jig plate gussets that are essentially cantilevered to a vertical plate. the gussets have moderate static loading, but have rather high dynamic loads (they're supporting...

    Non-laminar, non-fully developed flow in a duct

    I've recently been given the task of determining the percent increase in pressure loss for a system that will have several elbows added. The flow is very high (it's the supply for a gas-turbine engine). I hypothesized that by taking some peak measurements, I could approximate the current loss...
