    Advice on radial inflow turbine

    Hello All, where could one purchase a radial inflow turbine wheel and its manifold/nozzle assembly? I looked on the net but all I could find is this link. Would someone know what is the cost of such assembly for a turbine wheel with radius of 6cm (cold flow, about room temperature gas)? We...

    How to estimate mass flux through pipe

    Hello, I am trying to estimate the mass flux (m dot) of air (ideal gas, compressible flow) through adiabatic pipe. Can this be done without involving the velocity or Mach number? Forgive my ignorance... I can get the following: inlet pressure, inlet density, pipe cross-sectional area, pipe...

    Help needed in understanding pressure vessel nameplate

    Hello, Would you be able to interpret the nameplate info on this vessel? We are using an older (1960s) pressure vessel, the nameplate reads CRN. 4800.5. N.S.P. 3442. TS.55000. W.P.236.TEMP.354. SH.4375.HDS.387. UW.12.C.31.10.62. H.W.C. This is what we know: CRN is Canadian Registration...

    Filling up voids: when mating no longer helps

    Dear All, I am trying to fill up the void seen in the pictures. The void is between 2 solids which are mated and are constrained so the void can't be filled by rotation of one of the bodies. The crack is long and narrow and I don't have an idea how to "grow" one of the solids into the other...

    Filling up small cracks between solids

    Hello All, I am trying to align 2 solid bodies so they intersect without forming small-area faces. Then my goal is to combine them in a single volume and avoid "cracks" or short sticking-out edges. What is your strategy on that? I thought of: 1) build edges that coincide with the crack edges...

    Can't make 3d-line snap to helix

    Hello All, I have a helix, say, coming out of the front plane. Then I plot a 3d-line sketch. I am trying to either: 1) Make one end of the 3d-line snap to one end of the helix (in the very moment I am plotting the 3d-line) OR 2) Sketch the 3d-line, exit 3d-sketch, Edit the...

    Help on building helical surface with sweep

    Hello All, If someone could help with this situation... I am trying to create a surface sweep by using 2 helices. This is the step-by-step of what I tried: 1) create large helix: draw circle diameter = 2m in front plane; define pitch = 1m, revolutions = 5, start angle = 135.0deg, clockwise...
