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

nature of peer pressure perceive by adolescent‚ Brown‚ B.Bradford‚ et al (1896)‚states that 373 students in grades 7-12 were asked to indicate‚ on a 12-item index‚ the degree and direction of peer pressures they perceived from friends and acquaintances‚ and to describe their personal attitudes and behavior in areas corresponding to index items. Analyses revealed that peers were seen as encouraging misconduct less than other types of behavior. Females reported stronger peer pressure than males toward

air pressure of a football to the performance of a athlete? Alex Long Purpose The purpose for my experiment is to work out scientifically whether the air pressure inside a football effects the performance of a sports performer. There are several different types and brands of footballs all with different structures and pressure recommended for the ball. It would be interesting to find out the differences between the different companies and whether the air pressure inside

Pressure Distribution around a Symmetric Aerofoil Abstract: The following report is based on an experiment conducted to calculate the lift curve slope for a symmetrical aerofoil subjected to varying angles of attack. Pressure readings were taken at different points on the upper and lower surface of the aerofoil. The report concludes that maximum lift is generated between 12 º -15º‚ which is also the stall point. It also states that region close to the leading edge contributes most to the lift force

A manometer is an device employed to measure pressure. There are a variety of manometer designs. A simple‚ common design is to seal a length of glass tubing and bend the glass tube into a U-shape. The glass tube is then filled with a liquid‚ typically mercury‚ so that all trapped air is removed from the sealed end of the tube. The glass tube is then positioned with the curved region at the bottom. The mercury settles to the bottom After the mercury settles to the bottom of the manometer‚ a vacuum

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
