## Lab Report Marcet

. Theoretically, the values measured should be almost the same with the predicted values. Thus, conclusions about the change in thermodynamic properties of water undergoing different processes where drawn. Graph of T fg v dT versus P and versus P was also plotted. The electrical heater has a thermostat to limit the maximum heater temperature. The Marcet Boiler is used to investigate the relationship between the pressure and temperature of saturated steam in equilibrium with water at all temperature levels between the atmospheric pressure and 8 bars. The amount of saturated liquid was chan! The pressure and temperature were showed on the pressure indicator and temperature controller.

These things are the cause of the earth heating up, or global warming. Two of the most important thermodynamic properties of fluids being investigated in this experiment are pressure and temperature that both vary in response to changes in the energy of a system i. In cases like this, if the beliefs won't be the same then this is due to mistake that was manufactured in the test. The derived formulae and the data were used to calculate the slope. At a given pressure, the temperature at which a pure substance changes phase is called the saturation temperature Tsat. The boiler includes a special-purpose glass window. The units help to study the relationship between the pressure and the temperature of saturated steam in e uilibrium with water.

For sound engineering practice a mechanical Bourdon type gauge also displays the pressure. For a pure substance existing as a mixture of two phases, the Clapeyron relationship relates the pressure, heat and expansion during a change of phase provided that the two phases are in equilibrium. The Kinetic Theory of ideal gases - It is employed to express quantitatively the ideal gas model. As for the pressure and temperature of steam, both quantities are also proportional to each other which are proved by the calculations and the graph trends. Students will be able to control and monitor the heater power supply via a control panel. The increased of steam temperature was observed as the water was boiled. .

TecQuipment has checked the corrosion-resistant high-grade stainless steel boiler against the latest European safety standards. Graph of temperature against absolute pressure was plotted. The use of electricity accounts for 37% of total U. However, at certain points, the values are not the same. Derivation of the ideal gas equation from the kinetic theory The model used for discussing the molecular basis of the physical properties of a perfect gas. All the results were recorded and tabulated under the table below. The steam temperature was recorded until the steam pressure reached at atmospheric pressure while the boiler was allowed to cool down at room temperature.

The temperature of steam is recorded every time the absolute pressure increases by 0. The water inside the boiler is heated up by the electrical resistance and starts to evaporate. . Derive, from 1 and 2 , a. However, at certain points, the values are not the same. Cast Iron, Water Tube, Fire Tube etc. Valve at the feed port and the level sight tube were opened.

The main objective of this experiment is to determine the relation between vapour and pressure of saturated steam and also the vapour pressure curve. An ideal gas obeys the equation of state that relates the pressure, specific volume or density, and absolute temperature with mass of molecule and the gas constant, R. The gauge temperature and time taken is constantly recorded at an interval of 0. When the pressure increases, the temperature also increases. The pressure where equilibrium occurs at a given temperature is called saturated pressure. Increasing Pressure Steam Decreasing Pressure Mean Temp. When energy increases within water, the increasing of activities among the molecules enables the increase in the number of molecule escape from the surface until an equilibrium state is reached.

The water heater is protected from burnout by setting the maximum operating temperature with a temperature controller. This may because of the errors made in the experiment Table of Contents Abstract. The temperature where equilibrium occurs at a given pressure level is called saturated temperature. . This experiment explores the relationship between the saturation temperature and the corresponding pressure for water.

The steam temperature, gauge pressure at 1. Marcet Boiler is used to investigate the relationship between the pressure and temperature of saturated steam in equilibrium with water at all temperature levels between the atmospheric pressure and 10 bars. At lower pressure, the molecules become easier leaving the water surface while less energy required in achieving the state of equilibrium boiling point. Most thermodynamics substancessuch as gases and vapours are often referred as P-V-T substances. The experiments was performed carefully and followed all the instruction to get accuracy result. A few changes on the ideal gas equation of state allow its application in the properties of real gas. However, at certain points, the values are not the same.
