BOURDON TUBE PRESSURE GAUGE Bourdon Tubes are known for its very high range of differential pressure measurement in the range of almost 100‚000 psi (700 MPa). It is an elastic type pressure transducer. The device was invented by Eugene Bourdon in the year 1849. The basic idea behind the device is that‚ cross-sectional tubing when deformed in any way will tend to regain its circular form under the action of pressure. The bourdon pressure gauges used today have a slight elliptical cross-section and

EXPERIMENT: Pressure drop over a bubble cap plate. AIM : This experiment is conducted in an experimental test ring in which the effect of the variation in vapor and liquid flow rates on the pressure drop across bubble cap plates is simulated using air and water to represent the vapor and liquid respectively. THEORY: In a pilot tube the relation between the gas velocity and pressure drop is Where‚ is the differential pressure as expressed in the head of the fluid flowing. Where‚ ’=level

HIGH BLOOD PRESSURE The definition of High blood pressure is a measurement of the force applied against the walls of the arteries as the heart pumps blood through the body. The pressure is determined by the force and amount of blood pumped and the size and flexibility of the arteries. The blood pressure is continually changing depending on activity‚ temperature‚ diet‚ emotional state‚ posture‚ physical state‚ and drugs. The blood pressure is ussually taken while the person

report you will learn of how my group and I performed our lab on blood pressure and what the results mean. We found the blood pressure before and after sixty seconds of jogging in place to see the effects. We found that after the physical activity the subject’s blood pressure was higher. From this we take away that physical activity does have a significant effect on the heart and blood pressure. Background: Blood pressure is the measured force applied to the artery walls as the heart pumps. It

A barometer is a widely used weather instrument that measures atmospheric pressure (also known as air pressure or barometric pressure) - the weight of the air in the atmosphere A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water‚ air‚ or mercury. From the variation of air pressure‚ one can forecast short-term changes in the weather. There are two main types of barometers – Mercury Barometers newer digital friendly

The History of Blood Pressure Finding out someone’s blood pressure is very important. Johannes Müller once said‚ “The discovery of blood pressure was more important than the discovery of blood.” Someone’s blood pressure could be high‚ and no one would know. The reason being is that a person with high blood pressure‚ also known as hypertension‚ will usually have no symptoms. High or low blood pressure cannot be detected without being measured. High blood pressure could cause heart attacks‚ strokes

systolic blood pressure? Systolic blood pressure is the pressure exerted against artery walls created when the heart contracts to push oxygenated blood throughout the body. As blood pressure is represented by 2 numbers‚ systolic blood pressure is the upper number. A normal systolic blood pressure is 120 or below although it largely depends on the physical properties and capabilities of the individual. Q 2) what do you understand by the term diastolic blood pressure? Diastolic blood pressure indicates

attitudes‚ values‚ or behaviors‚ called peer pressure (Wikipedia). It might give some positive effects to teenagers when they are pressured toward positive behaviors‚ such as volunteering for charity or excelling in academics or athletics by their peers. Yet‚ many cases in peer pressure affects negatively to teenagers’ personality. As said by Wall Mueller (founder and President of the Center for Parent/Youth Understanding)‚ “The ugly reality is that peer pressure reaches its greatest intensity at just
