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...- balu1

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...- balu1

Anhydrous Piping Standard
Maybe this is a wrong forum for the question. Try those guys in "Chemical plant design & operations" forum.- balu1

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)...- balu1

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...- balu1

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...- balu1

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 =...- balu1

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...- balu1

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)- balu1

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...- balu1
