    Determining the Solute Concentration of a Potato Aim: In this investigation I am going to work out the sugar concentration of a potato. I aim to find this out by putting potato cores into various concentrations‚ measuring the mass before and after. Due to osmosis the potato cores will change in mass to make the concentrations at an isotonic level‚ helping us to work out the mass of the potato. I predict that potato in the weaker solutions will gain mass‚ because some water will be absorbed by the

    throughout the body. Blood pressure is the force that pushes blood against the blood vessel walls and delivers these essential elements to the body. The highest pressure is when the artery is maximally stretched and is recorded as the systolic pressure. The lowest pressure occurs when the artery recoils and is relaxed is known as the diastolic pressure. Mean arterial pressure is the average blood pressure and is an indicator on how well the perfusion to body tissues are. A blood pressure gradient is the driving

    Blood pressure is defined as the force of flow of blood inside the blood vessels. This measure is reported as two numbers such as 130/180 mm Hg. The first number is called systolic pressure and measures the push of the blood through the vessels as the heart beats. The second number called the diastolic pressure and measures pressure in between heartbeats or when the blood vessels relax. High blood pressure is one of the most commonly associated medical conditions with diabetes. US statistics reveal

    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
