Introduction Page 4 3. Equation 11 So k can be calculated as follows: Sources of errors are measurements or reading accuracy, room temperature and pressure, the stability of materials and calculations. When the liquid absorbed enough heat energy, it will change to vapour form. The market Boiler was used for this experiment.
The traces of steam remaining in the boiler can give results that are prone to error. Another aim is to understand the rate of change in temperature of a body when the body is heated and cooled.
When the pressure increases, the temperature also increases. These insulations play an important role in reducing the heat transfer thereby conserving energy and the decreasing the financial losses due to energy losses.
The saturated steam may drastically decrease the accuracy of the experiment. The experiment is a continuous process without any pause to take pressure and temperature readings.
Results and Discussion The experimental data collected are tabulated as follows: Overflow It removes any excess fluid and maintains the functioning of the boiler by controlling the amount of fluid inside the container.
For the heating curve: Background Theory In the course of this experiment and calculations, it is required to state certain laws. The state of equilibrium depends on the pressure between the water surface and steam. The Pressure Gauge It is used to compute pressure of the steam while the boiler heats up the steam to a certain temperature.
If we take the case of cooling, the decrease in pressure, decreases temperature exponentially.
Thermodynamics An Engineering Approach 5th edition by Yunus. This step is important to remove air from the boiler as the accuracy of the experimental results will be significantly affected if air is present. Since the graph is exponentially related the increment is noticed decreasing as we approach the close of the experiment.
As the steam is not allowed to exit, it will cause an increase in pressure and thus causing the temperature to increase. First consider the process of heating: Often the theoretically obtained temperature values for fixed pressure from the steam tables is used to compare the accuracy of the experiment.
Results and Discussion Page 14 7. Discussion It is necessary to remove air form the boiler as this could affect the accuracy of the experimental results.
However, real gas does not absolutely obey the equation of state. The error analysis is provided to describe the error that has reduced the accuracy of the experiment.
Thermodynamic also concerned about the changes in the properties of fluid. The experiment is carried out by heating the steam from 2 to 15 bars of pressure as well as cooling the steam from 15 to 6 bars of pressure.
The results obtained does compare with the theory and standard results. The pressure where equilibrium occurs at a given temperature is called saturated pressure. It displays the gauge pressure and should be converted into absolute pressure by adding the atmospheric pressure.View Lab Report - Marcet Boiler lab from BCHEM at SEGi University.
