Marcet Boiler

The apparatus used was a building block of Marcet kettle and water. The unit of Marcet tympanum consists of a stainless steel constrict vessel fitted with high pressure immersion electricalheater, control panel, a guard relief valve, water inlet port & valve, droning thermionic vacuum tube pressure gauge, temperature and pressure measurement devices.Before starting the experiment a quick inspection was performed to find out the unit is in meet operating condition. The unit of Marcet Boiler was later connected to the hot power supply. Valve at the break short away port and the direct spate tube were opened. subsequently that, the boiler was filled with distilled water by means of the yield port and the water level was madesure to be at active half of the boilers height. Then, the valves at the level whim tube were unlikable and the power supply is turned on.The temperature mastery was set at 185.0 °C which is slightly above the respect boiling point of the w ater at 10.0 sedan(abs). The valve at scarper port was opened and theheater was turned on. The valve at the level deal tube are made sure to be closed in(p) beforeturning on the heater as the sight tube is not designed to withstand high pressure andtemperature. The rise of move temperature was observed as the water boils. The steamfrom the valve was allowed to come out for 30 seconds before the valve was closed. Thisstep is important to remove aviation from the boiler as the accuracy of the experimental resultswill be significantly affected if circularise is present. The steam temperature, gauge pressure at1.00 restraint (abs) and time see for the steam to reach 1.00 bar (abs) were enter. Thisstep was repeated by increment the interval of pressure with 0.5 bar (abs) until the steam pressure reaches 10.0 bar (abs). After that, the heater was allowed to cool down to roomtemperature. All the results were enter and tabulated under the table below. Graph of temperature agai nst absolute pressure was plotted. invento! ry of the slope of the graphwas made.
