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

Hormones can react to increase blood pressure when it becomes low‚ the sympathetic division of the autonomic nervous system uses several ways to temporarily increase blood pressure when it has dropped for example during the fight or flight response. During the response‚ the sympathetic division is needed to stimulate the adrenal glands to release the hormones epinephrine and norepineprine which stimulate the heart to beat faster and for blood to flow more forcefully‚ this effect makes most of the

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

EFFECT OF ATMOSPHERIC PRESSURE ON THE ENVIROMENT THE BIOSPHERE Variations in atmospheric pressure can present special problems for the respiratory systems of animals because atmospheric pressure affects the exchange of oxygen and carbon dioxide that occurs during animal respiration. Normal atmospheric pressure at sea level is the total pressure that a column of air above the surface of the Earth exerts (760 millimetres of mercury‚ or 1 atmosphere)

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

do a manual blood pressure (BP) to make sure it was not a mechanical error from the automatic machine and recorded 99/75. His other vital signs were in between the flags. I asked my patient how he was feeling‚ he said he felt fine. I told him his blood pressure was a bit low and if this was normal for him. He said it has been low a bit recently. I asked him if he could have a glass of water and explained how this can help in elevating his BP so he had a glass and a half of water. I also made sure

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
