N) of another molecule. THERMAL ENERGY Thermal energy is the energy of a body arising from motion of its atoms or molecules. It is directly proportional to the temperature of the substance. THE GAS LAWS Boyle’s Law At constant temperature‚ the pressure of a fixed amount of gas is inversely proportional to its volume. P1V1 = P2V2 Each curve corresponds to a different constant temperature and is known

between the pressure and temperature of saturated steam in equilibrium with water. 2. To determine the vapour pressure curve. Introduction Properties of a fluid can change when heat and work are applied to it. There’s an interchange between the fluid and its surroundings when heat and work are applied according to the study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas obeys the equation of state that the pressure‚ specific

tappings required by the pressure sensors‚ additional tappings are included in the ducts to allow appropriate calibration instruments to be connected. The flow of air through the compressor is regulated by a throttle control device installed at the exit of the discharge duct. Rotation of the collar opens and closes a variable aperture which allows the head/flow produced by the compressor to be varied.

retains a pressure that is constant between defining limits during both static and dynamic situations. In this context‚ ‘constant’ refers to maintaining a pressure that is continually within the margins of the drilling window. Typically within CBHP MPD operations‚ an automated system such as Weatherford’s Microflux Control system is used to measure and apply the required level of surface backpressure. The following describes the basic mathematics behind this system. [2] Well-bore pressure during

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

of pure water in the data table. Letting the water boil will decrease the mass of the water present in the calorimeter. Note that the boiling point may be different than 100°C if the atmospheric pressure is not 760 Torr. The current atmospheric pressure for the day can be checked by selecting Pressure on the LED meter on the wall. 5. Drag the weigh paper to the calorimeter and add the NaCl. Wait 30 seconds for the salt to dissolve and then turn on the heater. When steam first appears

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
