has just had a new Point of Sale system input which meant we had to train 150 staff over two days which‚ as you can imagine‚ was highly pressured giving the short turnaround. Can you give an example of when you have been put in a similar high pressure situation and how did you deal with it? 9/ What does confidentiality mean to you? 10/ What does equal opportunities mean to you? N.B. If there is time‚ invite the candidate to ask any questions they may have about the role and organisation

Boyle’s law‚ Pascal’s law‚ and Archimedes’ law. Boyle’s Law states that under conditions of constant temperature and quantity‚ there is an inverse relationship between the volume and pressure for an ideal gas. Pascal’s Law states that if pressure is applied to a non-flowing fluid in a container‚ then that pressure is transmitted equally in all directions within the container. Archimedes’ principles is an upward force on an object immersed in a fluid (a liquid or a gas)‚ enabling it to float or

consume O2 and give off CO2 during the manufacturing of ATP. (Jenkins‚ 2010) Air moves into the lungs when the air pressure inside the lungs is less that the air pressure in the atmosphere. Boyle’s law states that‚ “The difference in pressure caused by changes in lung volume force air into our lungs when we inhale and out when we exhale.” Pg.748 if volume increases‚ outside pressure must decrease. This process involves the diaphragm muscle which increases‚ during forceful inhalations expanding the

Boyle’s Law Experiment Aim To show that Pressure is proportional to the inverse to volume Method A gas syringe was attached to a pressure sensor. The pressure sensor was calibrated‚ assuming the atmospheric pressure at the time of the experiment was 100kPa. Differing volumes of gas were created in the gas syringe and they were recorded as were the corresponding values of pressure at that particular volume. The volume was varied between 20cm3 and 75cm3. Results A set of readings was obtained

the more you put in‚ the higher the pressure). If you’re really strong you can compress a solid mass as well. But no matter how much pressure you apply onto a liquid‚ it isn’t possible to compress it. Now if you put that liquid into a sealed system and push on it at one end‚ that pressure is transmitted through the liquid to the other end of the system. The pressure is not diminished. Aircraft Hydraulics Definition It is a system where liquid under pressure is used to transmit this energy. Hydraulic
