    Gland Seal Thermal Stresses

    Unfortunately this is not my field so I can't answer your question. Not even make an engineering gues since I don't even know what a "gland seal" is. Not to mention HRSGs. But you should also try Engine & turbine engineering forum since there may be some more gurus not visiting this site...

    how select diameter of piping to carry plastic by gravity ?

    It probably depends on how large flow of polyethylene pellets you need. Assume, just for the sake of discussion, that those pellets can reach velocity of 0.4 m/s in free fall (very light material, high aerodynamic losses, have you ever seen a chicken's feather falling). In that case volumetric...

    Anhydrous Piping Standard

    Maybe this is a wrong forum for the question. Try those guys in "Chemical plant design & operations" forum.

    Furnace Survey

    The proper procedure in aerospace industry is to get approval from independent, accredited (ISO 900X approved) source. They install their master TCs (of known accuracy, supposedly high) in your furnace, covering the working space (e.g. 10 TCs for 1 cu.ft. or per some ASTM spec if there is one)...

    How to obtain technical report in AFFDL

    This paper states the same reference you are asking for: www.crhsc.umontreal.ca/dreams/ Nielsen%20Reprint_Brain%20and%20Cognition_41_200-212_1999_EEG%20coherence.pdf It is correct that AFFDL stands for Air Force Flight Dynamics Laboratory but it doesn’t necessarily mean that all AFFDL...

    ballistic rocket flight path

    This is not so simple. I imagine that you have to include a lot of effects if high calculation accuracy is required. Wind is only one of them probably important during initial phase of flight only. Lets say until first stage rocket separation. You may probably assume constant speed of let...

    when a elastic material like rubber

    Pressure in gasses is considered an indicator of potential energy, a kind of specific potential energy, if I may say so. If there is a vessel, V capacity (volume), containing a gas under pressure P (gauge pressure) its potential energy due to pressure difference to ambient pressure is: Ep =...

    gas turbine load / speed questions

    Gas turbines (GT) are used on modern tanks. They have been used on some locomotives and trucks but never a steam turbine (ST) has been used (except maybe for some experimental purposes). They are used only on large ships as well as gas turbines on smaller battle ships. Obviously size of a...

    Best way to measure velocity approx 5m/s +- 0.1m/s

    You are right that a hot wire anemometer would be better than a pitot in this case. But +/-0.1m/s accuracy could be a little bit too much I believe. It is exactly at the best assuracy limit of +/-2% (see http://www.topac.com/anemometer.html)

    Vortex Sheader

    I assume that at lower Re numbers those vorteces are not regularely generated or they are not stable, disappearing quickly.

    Orifice flow energy relation

    Not quite sure that I understand the problem but I would like to state a couple of notorious facts for any incompressible flow: 1) Power (which is energy "flow" i.e. energy supplied per unit of time) equals: Q*p (volumetric flow multiplied by pressure) 2) Temperature change is...

    VDI heat atlas required

    What on Earth is VDI? It could even be Very Distinctive Individual(s)!?! Just teasing. Sorry, but I couldn't help it.
