    Shell & Tube Falling Film Evaporator Nickel Tubes Collapsed

    An unfortunate incident happened at our triple effect caustic evaporator (32w.t% to 51w.t%). The third effect (highlighted red) where major steam (~12-13bar depending on flowrate) assisted evaporation take place, here for some reason Ni tubes get severely collapsed, while the plant was offline...

    Sir, what further information should I share. I think am pretty much clear

    Moist Chlorine & Hydrogen Psychrometric or Mollier Chart

    In our electrolysis of brine, Cl2 & H2 are produced as gaseous products along with aqueous NaOH. In this scenario I require what amount of maximum moisture can Cl2 or H2 hold up at specific temperature & pressure (precisely 85celsius & 1.2bar absolute). Two coolers (shell/tube exchanger with...

    Negative & Positive Shear Factor

    My question relates to constructional geometry & matrices aren't to be involved in the solution because stated Math level is up to O Levels... The figure below shows shear with y=3 as invariant line & shear-factor of 3 My question is if you are provided the original polygon & asked to do shear...

    Difference b/w Retrorockets & Vernier thrusters

    Retros used for deorbital/orbital insertions..ok thnx got it. But verniers used for altitude control?...ths makes no sense in the presence of large primary nozzles which are to take care about altitude. I thing verniers are for orientation control.

    Difference b/w Retrorockets & Vernier thrusters

    these two term are different but from photos the two components looks quiet alike..i had done some search but can't grasp ACTUAL difference b/w the two as both are small rocket auxillary nozzles... by the way I have been able to discover what is in the first photo but can't identify a...

    Small Liquid Rocket Engines for Sale | Glow Fuel Propellant

    for safety measure I vote for liquid rather than solid rocket engines...atleast via a safe valve (if something goes wrong) you can put off the supply line of fuel/oxidiser

    Exploring Air-Flow Characteristics on Swept Wings

    regarding ambiguity b/w fences & GasterBumps(I can't find any picture. of the latter) http://en.wikipedia.org/wiki/Wing_fence Regarding 2nd question. In my understanding the pure-delta wing is highly prone to stall at high AoA reason is the spanwise flow! This problem thus can be...

    Exploring Air-Flow Characteristics on Swept Wings

    YouTube - Air-Flow Characteristics on a 40 Degree Swept Back Wing the above video indicates that as the angle of attack rises the span-wise airflow rises & more probably the leading wing edges will stall first. Also notice that no appreciable change in airflow occurs at the root(attachment...

    Which is the airfoil having highest lift to drag ratio?

    for highest lift you must make something like B-2; I.e blending fuselage with wings in such a way that the whole resulting shape acts like an airfoil! http://img99.imageshack.us/img99/9771/flyingwinggoogledocs129.png [Broken] Uploaded with ImageShack.us see the sideview of B-2 just like...
