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

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...

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...

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.

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...

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

^^ Thnx both of you for your contributions

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...

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...

you got that right:)

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...

There occurs various hybrid wings; however currently the most researched is Morphing Wings

Guys,, but their must be some difference b/w choosing + over x

talking about Drag parameter only; wht you suggest; either + or X configuration will have more than the other??

+ or X Rear fins?? http://img124.imageshack.us/img124/2054/c6xxvp3.jpg [Broken] Notice the folding rear fins and fact that they are at 45 degrees X relative to the intake. [PLAIN][PLAIN]http://img208.imageshack.us/img208/363/c602xxxnm5.jpg [Broken] But clearly the rear fins r "+" Now...

Use maple its just great

you need to see Nat Geo documentary on it>>search through net

What does this bold part means. The placement of air intakes with respect to cockpit is fairly equal that of Su-25/30/35 & F-15/35/22 With the exception of F-16/J-10(a copycat of F-16) all modern aircraft had 2 side air intakes. including the newbaby JF-17

Can anybody given me images of these 3 types of air intakes; I am fed up googling it

& wht does ths mean??

Air Intakes?? Source: Russian Fifth-Generation Fighter Technology Demonstrators Yefim Gordon Original translation by Dmitriy Komissarov Question is simple; is Soviet thinking while choosing from 3 given air intakes is correct & why US think otherwise??

I assume starter motor are predominantly for compressors (even though turbine is attached from a coomon shaft) ; because after combustion start turbine start to move & carryout combustion one must move compressor such that air is sucked & compressed to combustor. However once process is...

Thnx for replies. If such be the case Why TURBOJETs are preferred over Turbofans in Antiship missiles.(provided turbojets be more prone to IR detection against relatively cold sea)?? With the exception of (as far as I know ) RGM/UGM-109B Tomahawk Anti Ship Missile (TASM) - radar...

People I believe ht there must be some difference in thrust profiles of a cruise missile that is launched from a aircraft fling at 1) 1.6Mach 2)~16km altitude compared to a missile launch from sealevel with 0 initial speed

Provided that we have got two different missiles by name(A & B) but yet they have in common the guidance system as well as the engine say a turbofan; can they be called a single missile having two versions i.e air launched & land launched?? If not does this mean that though both have...

[PLAIN]http://en.rian.ru/images/16070/97/160709799.jpg [Broken] why is nosecone detaching at such a low altitude

^^Thnx

@mugaliens Thnx I just am a student & questioned it out of curiosity. However; can any plane cruise at low altitudes which is beneficial for stealth warplanes. I think cruising/super-cruising only is obtained at very high altitude

@boneh3ad Thnx by the way when applied to warplane what is cruising speed??

Source http://en.wikipedia.org/wiki/Cruise_(flight [Broken]) then totally opposite statement What essentially is cruise speed

@hydrogen1 Thnxxxx

Thts what I am asking whynt it ain't the accumulation term; verbally explain please

ok I didn't undertstand answers to this good question

here it is

In the first equation: substitute Vx = Vr * Cos (theta) Vy = Vr * Sin (theta) Vz = Vz but how do I get V(theta)

I can't even start solution No idea how to convert subscipt from vx to vr and or to vtheta?
