What i understood from your comment is that the reaction force induced in the walls is now responsible for creating the weight effect(weight of air column). But suppose if there is no reaction induce in the wall as in case if the air is filled in a chamber in 0 gravity. what would be the...
But now when you have sealed the room you have created a partition between air inside room and the air outside.
because of this partition no external force(weight of air column) is now acting on air inside room. hence the pressure inside must be = (the pressure before sealing)-(weight per unit...
Thanx for the response...
But if the the pressure is the weight of air column, then why it is not affected by gravity..?
also for the box example, consider a room. If an open room is sealed from all sides without pumping or removing air from inside, the pressure inside the room must...
Hey frndz,
Can anyone explain me what is atmospheric pressure? How it acts? And is there any relation between Atmospheric pressure and Gravity...:confused:
What i have in my mind is that Atmospheric pressure is the Weight of gas in the atmosphere...so the pressure at any surface is the...
Spherical Magnet...!
Hello Everyone,
There is a Doubt constantly raising in my mind...it may sound stupid but i was wondering if it's possible to produce Perfect SPHERICAL Magnet...if so how one can determine its pole. I mean Where are the north and south pole...?
see the link below
i don't think any external medium is used here...
The same thing happen with us few days back but with a soft drink...
the waiter brought an bottle kept in freezer for 2-3 days, as he kept the bottle on the table bubbles started coming off its bottom and the liquid...
Hello Frndz,
Yesterday I watched i video on You tube, The video shows a beer freezing in 2 sec. I was wondering if the video was fake or it is possible to do so. If it is true, can anyone tell me whatz the logic behind this..?
Thanx

Hey Matt
The Cp value for the exhaust gas is approx 1.318 KJ/Kg/K. this value may change, so if you can give me some general formula in terms of cp it will be better for me.
Thanx

Thanx Matt
The pressure of the Exhaust gas in 4 bar max, the shell thickness is 36mm, flow of the exhaust gas is for not more than 200Sec, we have to decide the inlet an outlet temperature of the cooling water.
the purpose of cooling is to protect the shell from heat and not to cool the...
Hello Everyone,
I am Mayur
I am working on a system, in the system there is one diffuser through which exhaust gases at 3000K are flowing at a rate of 170Kg/s. The material of diffuser is Stainless Steel. The diffuser is double walled type with cooling water flowing between the walls.
I need...
