When water is heated to a certain temperature, it starts getting converted to a different phase. WebThe wet bulb temperature of air is also measured by the ordinary thermometer, but the only difference is that the bulb of the thermometer is covered by the wet cloth. If some of the heat energy is absorbed from the dry saturated steam, the steam becomes wet.

We know that to determine the temperature of any system, the thermometer must be brought to thermal equilibrium with an arbitrarily chosen standard system in an easily reducible state. Coming back to steam table use, we can use either temperature tables or pressure tables. The values given in the tables are for one kg of dry saturated steam but these values can also be employed for wet steam calculations. Actually it has much broad definition in thermodynamics but for 1styear BME students this definition works just fine. Image credit: NASA/JPL-Caltech/Alex Novati. For example- if the pressure of saturated steam is observed by the pressure gauge, its temperature can be found from the steam tables in which the results of the various experiments have been tabulated. If we know the temperature and the pressure in the expansion chamber then we can tell if all of the steam has changed to vapour. It contains just sufficient heat energy to maintain all of << 10.9. 8. The liquid form of water gets converted to gaseous phase called as steam. Finally, the system does no external work, i.e. Repeat this for other pressures and temperatures and draw a curve through the points obtained. >> Similarly if heat is removed more of the vapour condenses but the temperature will remain constant. If superheated steam is brought in contact with water it will give up part of its heat to the water. If the steam at pressure P1 had been wet, with a dryness fraction of x, the entropy of evaporation would be . View Answer, 2. Steam contains more energy as it has both sensible heat and latent heat of vaporization. Before uploading and sharing your knowledge on this site, please read the following pages: 1.
