    Axial Compressor/Turbine - Methodology to estimate thrust forces generated?

    I'm trying to perform some base level calculations to estimate axial thrust forces within a gas turbine engine. Looking at this, I see four key components to the forces: 1. Compressor Axial Thrust - i.e. forces generated at each stage of the compressor 2. Turbine Axial Thrust - as item 1, but...

    Flame Arrester - What Size Required?

    I'm hoping somebody can be of help with a flame arrester query I have. Basically I need to find a suitable flame arrester which will allow a unit to meet Atex regulations for group IIB2. Effectively what I need is an arrester element that is as small as possible in length and of diameter no...

    Impact Pressure/Energy for indentation

    I'm trying to find what pressure or energy would be required to indent copper by 1mm. To be more specific it would be for a piece of copper sheet that was about 1mm thick and resting on some dust like particles so nothing too hard underneath. It would be struck by a pin like object that had a...

    Partial Threading of round bar

    How do you partially thread a bar in solid edge? I need to thread about 50mm of a 150mm bar but it won't allow me to do this as it simply threads the whole bar even when I use a finite value for it. Anyone able to help? Thanks.

    Small Gears

    I'm currently using solid edge for a uni project and very much teaching myself as I go along, but I've hit a problem. I want to put a small gear into my part (about 20mm diameter) but when I try and create it all I get is a cylinder with no teeth. I can manage to create larger diameter gears...

    Viscosity of 15w-40 at room temperature

    Would someone be able to help me out and tell me what sort of range of viscosities 15w-40 could fall into at approximately 20 degrees centigrade. I know that there can be a lot of variation but if someone was able to either give me a range of values it would be between or a link to this...

    Analysis of Stokes law?

    Hi, I am currently involved in an investigation in which I am looking at stokes law for measuring the viscosity of different liquids. I realise that stokes law only applies with infinite boundaries (i.e. a tube infinately wide and long) however what I wanted to invvestigate was what sort of...
