CHAPTER II FUNDAMENTAL THEORY When A.PROSES 12 volt car fan evaporation in a boiler contained some

PREFACE Thank God, I thank God Almighty 12 volt car fan for His blessings and grace, so that I can finish the report entitled "STEAM EXPERIMENT QUALITY TESTING" is well and on time. I wish to thank Mr. Rufinus 12 volt car fan Nainggolan who has guided 12 volt car fan us in doing this lab, as well as friends who are willing 12 volt car fan to implement this practice well. This report is about how to carry out the lab so that the reader understand how the real quality of the steam, because this report 12 volt car fan collated systematically complete and clear. Analysis of the data was made as clear as possible so that the reader can understand. The report "STEAM EXPERIMENT QUALITY TESTING" is based on the research is accurate and clear theoretical material. But this writing is far from perfect, then I strongly expect criticism and suggestions from readers. That's all and thank you.
TOPIC: STEAM QUALITY TESTING / DROUGHT FRACTION OF STEAM (AND throttling Separating Calorimeter) REAR A.LATAR combination separator and inclusion Calorimeter is used to determine kulaitas vapor (steam dryness). Separator Calorimeter is a tool to separate the water content of the steam through a mechanical process. Menggandung still wet steam water separator is passed to the calorimeter, because the density is greater than water vapor, the water vapor will tend to be thrown. This water is collected and the amount can be calculated. Relative vapor contains no water has been supplied to the throttling calorimeter, so the pressure drops. Pressure after throttling to just below atmospheric 12 volt car fan temperature. This causes the steam to be dry. By measuring the temperature and pressure of the steam end, the rate of steam dryness can be calculated. Because these two types of calorimeters have limitations, then used a combination of separation and throttling.
B.TUJUAN EXPERIMENT The purpose of this experiment is the steam quality: students are expected to know the function of separating equipment and Calorimeter. that students know the working process of separating and throttling Calorimeter so that students can know the vapor pressure before and after the throttle and determine the exit temperature disharge) of the throttle through measurement tools installed so that students can know the amount of water separated from the steam coming through the separator and measure the water coming out of the condensate which is collected by the measuring cup so that students can draw the schematic experimental apparatus 12 volt car fan to allow students to understand the function of separator sebaga condesor and testing tools in order to calculate the quality of the student so that the student can understand the vapor steam table lists and reading in the analysis of experimental work that students can make steam quality 12 volt car fan test report.
CHAPTER II FUNDAMENTAL THEORY When A.PROSES 12 volt car fan evaporation in a boiler contained some amount of water and we noticed the water molecules, the water temperature at the time to kelvin or Celsius. 12 volt car fan The water molecules move freely to and fro in the environment with the velocity V0 meters / sec. The molecules are in motion to and fro will not be able to leave their environment, ie water because of the motion of attraction itself. If the boiler that heated the boiler temperature Ti and turns it into the velocity of the water molecules will increase to Vi. However, it has not been able to break away from the environment. If the boiler hot water temperature is getting bigger then reached the mark while the velocities of the water molecule has reached Vd. Water molecules to break away from the environment and turns into vapor molecules that speed exceeds the original motion of water molecules. This process is called 12 volt car fan 'the process of evaporation ". Water molecules turn into vapor molecules or can also be called the boiling water, because the water's surface becomes turbulent. The temperature of the water by the time it reached the boiling temperature is kelvin mark. B.DESKRIPSI Separating Calorimeter is an equipment of a mechanical process, in which the wet steam entering directly past the arrangement in the form of blunt blades. At the time of passing through the blades, the inertial forces of water contained in the steam is reduced and prevent it from ending up in the resulting water vapor will fall and accumulate in the tube (chamber). Throttling Calorimeter is an influx of equipment steam into the tube through the orifice so that the pressure dropped to slightly above atmospheric pressure (open flow). This causes the steam superheat. Through the measurement of pressure and temperature steam output, then the steam dryness fraction can be calculated as the steam leaving the tube separating the water content can not be separated entirely.
Separating Calorimeter and the throttle is very important to know the dryness fraction uap.oleh Therefore, it can be done with
