The crew live and work inside the pressure hull. It must be strong enough to withstand the pressure of the water at the depth the submarine is designed to operate. When the air tanks are full of air the submarine will float - usually submarines are designed to float on the surface quite low in the water (only a little freeboard). When the submarine dives (submerges) water is let into the tanks; to surface again air is blown into them. This air must be stored inside the submarine in compressed air

Peer Pressure “Come on grab it hurry just grab it‚ it’s easy to steal the video game and I will let you play it first hurry‚ and grab it.” Peer pressure is basically someone around you who is trying to get you to do something you are not comfortable with‚ or something that is against your standards. For instance trying to get you to smoke‚ or drink with them is something you may not be okay with. Although some might say all peer pressure is bad I would argue that because peer pressure can be

Peer Pressure‚ Cause and Effect Peer pressure has become a big issue in our modern world. Many people experience it every day and a lot of times it leads to bad decision making. Peer pressure can affect you in the long run and knowing how to say no to certain things can sometimes save your life. There are many causes to peer pressure but the more noticeable one would be just pure excitement. Say that your peers are jumping their bikes off ramps and they ask you to try. You

A pressure gauge is an instrument that measures the pressure in a vessel‚ a line‚ or whatever the pressure gauge is connected to. A Bourdon gauge consists of a C-shaped pipe with one end closed and the other end attached to a chamber whose pressure is being measured. When there is a pressure difference between the inside of the pipe and the outside‚ there will be a net force acting on the C-shaped pipe which will either try to curl the pipe into a tighter C shape (if the pressure in the pipe is

overall purpose of the experiment is to observe the change of pressure as three different gases; N2‚ He‚ and an unknown gas effuses through a pinhole into a vacuum environment. Each gas has a different pattern of changing the pressure depending on its molecular mass‚ which is related to the kinetic theory of gases‚ where heavier gases (N2) effuse slower than lighter gases (He). The experiment setup was prepared‚ measurement of change of pressure as a function of time were recorded. After performing two

Positive Peer Pressure Whenever you hear the word peer pressure every one immediately refers to the negative influences. Have you ever explored the possibilities of positive peer pressure happening in people’s lives today? There are several examples of peer pressure out there that are positive‚ experienced mainly by teenagers that go unnoticed. The big one that needs to be focused on is the influence of not smoking‚ doing drugs‚ and drinking alcohol. Then the two other examples that we are going

Peer Pressure What is peer pressure? Adolescents often times deal with pressures from homework‚ love‚ money‚ parents and teachers. However‚ one of the things that pressures us the most is how to fit in with our peers. We call it peer pressure. Simple enough‚ it is exactly what it says pressures from your peers. Peer pressure is when you do something either because they have persuaded you or because all your peers are doing it. Do you remember the last time your parents declined your

blood vessels. The strength of this pushing is your blood pressure. If the blood pressure is too high‚ it puts extra strain on your arteries (and your heart) and this may lead to heart attacks and strokes. Having high blood pressure (hypertension) is not usually something that you feel or notice. It does not tend to produce obvious signs or symptoms. The only way to know what your blood pressure is‚ is to have it measured. Blood pressure is measured in ‘millimeters of mercury’ (mmHg) and is written

EXPERIMENT-1 Pressure-Temperature Relationship for Steam OBJECT: The objective of this experiment is to determine the relationship between saturation pressure and saturation temperature of the wet steam. APPARATUS: Pressure-temperature apparatus with pressure gauge and thermometer. [pic] THEORY: In order to determine the relationship between the saturation temperature and pressure of wet steam it is necessary to obtain a number of corresponding values of the
