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)

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

illegal drugs are peer pressure and depression. These concepts will be expanded upon in detail in this paper. Peer pressure is one of the major reasons that teens abuse illegal drugs. Peer pressure is when another person in this age group persuades someone else to do something they don’t want to do. (Williams‚ Rob) This happens often among friends.

Gas Pressure and Volume Relationships Exp. E-1A A. Obtain a pressure-measuring device as indicated by your lab instructor. Obtain a 60 mL syringe‚ fill it with air‚ and connect the syringe to the gas-measuring device as indicated in the figure. Test your apparatus for gas leaks. If you can’t eliminate all leaks‚ see your lab instructor. B. If necessary‚ calibrate your gas-measuring device as indicated by your lab instructor. Fill your syringe to the largest volume mark on the syringe and reconnect
