What is difference between penstock and pressure shaft?
Pressure Shaft is designed to resist Internal as well as External Pressure, but the Penstock is designed to resist Internal Pressure only. - Saravanan.S
What is pressure gradient?
It is a difference in pressure
Boiling involve a chemical property?
it is more of a physical property depending on the strength of the substances' atomic/molecular columb forces, and the difference between internal and external pressure. so no it does not involve chemical property
What is the pressure difference between the external air and pleural cavity when inhalation just begins?
No
Why you do not feel air pressure although there is a tall column of air above us?
If the human body was hollow and contained a vacuum, we would then feel the air pressure. However, our lungs contain air, so the internal pressure is the same as the external pressure. Air pressure is perfectly balanced everywhere it is in contact with us, and all of our internal fluids, blood, lymph, etc., are under pressure, and balance the pressure that the air exerts. If a human being were to be exposed to the vacuum of outer space, our pressurized internal fluids would explode. We can only feel a difference in pressure, we do not feel perfectly balanced pressures, within and without.

Is pressure internal or external?
It can be either.
What is pressure gradient?
It is a difference in pressure
What is the scientific name of something that causes stress?
internal or external compelling pressure
What are possible internal and external influences on your food choices?
The possible internal and external influences on your food choices include; External: advertising peer pressure aroma ease of access Internal: general hunger perceived deficiency (yearning for a particular food or flavor)
What happens when a gas is stretched?
You cannot stretch a gas. If you extend the volume in which some gas is enclosed you are working against the difference in between the external atmospheric pressure and the internal pressure of the gas. As you increase the enclosed volume, the pressure inside there falls and you have to work harder.
Why does the eardrum may burst inwardly if you are in a deep sea but it may burst outwardly if you are in space?
In the sea, the external water pressure is greater than the ear's internal air pressure, so it implodes. In space, the external vacuum is less pressure than the ear's internal air pressure, so it explodes (or is 'sucked' into space.)
Can water pressure kill a human?
Our bodies have an internal pressure equal to that of the atmosphere (101000 pascals). Once the external pressure on you body exceeds this internal pressure enough your body will implode. This external pressure can be provided by water. Depending on how you go about going that far below water and the specific tolerances of your body a deadly depth can be from 500 to 1200 feet.
What is the difference between pressure and stress?
Pressure is the external force acting over a unit surface area of a material. Stress is an internal force acting over a cross sectional area within the material. It may also be thought of as the internal resistive response of a material to the applied external pressure. They both have the units of force / area. think it as- suppose we have a cubical solid mass. we apply external force of few magnitude on it and this force will try to deform the cube. at the same instant an internal force will generate within the cube that will try to maintain the shape and size of the cube i.e. this internal force will work against the applied external force. this induced force within the cube is stress.
How does the octopus prevent brain damage despite the lack of a rigid braincase?
Octopus internal pressure equals external pressure and there is no crushing.
If you infaleted a balloon and then exposed it to outer space what would happen?
It will pop because the internal pressure will be much greater than the external pressure.
Is the pressure of a gas or external pressure used when calculating the work done by a gas?
The pressure of the gas is used. Newton's third law requires that the pressure exerted by a gas is equal to the pressure exerted on a gas.You might be wondering, then, how it is possible for the internal pressure to be different from the external pressure. In fact, the difference will be made up for by the piston moving between them. Since we must assume (to avoid infinite accelerations) that there is a piston of finite mass intervening between the two gases, the excess work done (due to the difference in pressures) will go into the kinetic energy of the piston.
