At 35,000 feet, a human would suffer severe oxygen starvation without a pressurized cabin. Also known as "death". A pressurized cabin in a commercial - or military - airliner is essential at high altitude.

What is PWR or BWR?
PWR = pressurised water reactor. BWR = boiling water reactor
Does temperature of a gas increase or decrease under pressure?
If a gas is pressurised then the temperature will increase.
What effect does atmospheric pressure affected have on your body?
the atmospheric pressure has no effect on our bodies in normal conditions this is because our blood is pressurised thereby equalising the force from both directions. this is why astronauts have pressurised space suits to prevent their bodies from bursting in space where the pressure is not being exerted on them.
The moderator used in the nuclear reactor at Madras atomic power station in Kalpakkam is?
Heavy water(PHWR)--Pressurised heavy water reactor
What is used to slow down an aircraft?
If the aircraft is coming into land then the hinged part of the wing called Flaps are lowered to increase the amount of Drag over the wings. If you think of drag as an air-born form of braking then Flaps down means the aircraft the aircraft slows but increases the maneuverability the pilot has over the aircraft. If the aircraft is on the ground then wheel brakes are very useful
What is difference between hovercraft and aircraft?
Basically, an aircraft flies, a hovercraft doesn't. An aircraft relies on aerodynamic lift, a hovercraft is "lifted" by a cushion of pressurised air trapped in the plenum chamber.
Why must airplane cabins be pressurized?
Because at altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurised so that the internal pressure is equal to that at about 7,000 feet.
What is the advantage of using a pressurised nuclear reactor?
In a pressurised nuclear reactor the temperature is very high, which cn be accepted as a point for this.
Why do an aeroplane are often 'pressurised'?
As aeroplanes fly high in the atmosphere, where the air is thin, the inside has to be pressurised to allow the passengers and crew to breath.
How do people get in space?
They take it with them, in pressurised tanks.
Can you take pressurised cans onto flights?
no
Why can you wear ordinary clothes in a space shuttle?
because it has been pressurised in a similar way (outcome) to how a commercial airplane is pressurised for passengers to fly at altitude.
What does it mean when the air in airplanes are pressurized?
The air in an aircraft needs to be pressurised so that the people within the cabin don't pass-out from oxygen starvation at higher altitudes. The atmosphere can be described as a load of blankets wrapped around the world, the bottom layer has all the weight from above and is squashed, but as you go further up, there is less pressure on the blankets. this is the same with air... at sea level there is plenty of oxygen in the atmosphere to breathe, the higher you go the more sparse the air becomes and less oxygen is available for breathing. Aircraft are usually pressurised to the equivalent of 8,000ft as this is a safe threshold for breathable air.
What is the necessity of pressurised cabins in aeroplanes?
no your gonna die
Does the temperature of nitrogen increase when it is pressurised?
Generally, yes
Experience of working in a pressurised and busy environment?
yes
What brewery was first to introduce keg beer?
Keg beer is a term for beer which is served from a pressurised keg. Watney's (UK) started with an experimental pressurised beer Red Barrel which was served in a pressurised Keg rather than the traditional Cask (barrel) in 1936. The use expanded rapidly circa 1960
