If heat is added to the wet steam temperature _________a) raises immediatelyb) decreases immediatelyc) raises after sometimed) none of the mentionedAnswer: cClarification: When heat is added to the steam immediately the liquid particles try to evaporate and form saturated steam only after that the temperature starts rising. Again a throttling expansion will be represented by a horizontal line on this diagram, as throttling process is a constant enthalpy (isenthalpic) or total heat process. The consequences of using wet steam in sterilization are: Regardless of the amount of moisture in microorganisms, saturated steam effectively transfers heat and kills microorganisms. Thermal -II Question BANK - DIPLOMA STUDIES MECHANICAL The throttling calorimeter makes use of the fact that the enthalpy before throttling is the same as that after throttling, in order to determine the dryness fraction, x, of the steam passing through the calorimeter. Similar constant pressure lines can be drawn for superheated steam at other pressures. So, total heat content by steam is termed as its enthalpy. Schematic diagram of the diffusion battery 16 0 obj The final condition of the steam after expansion can also be read off from the diagram.

In a throttling process, which of the following parameters remains constant? When it reaches cooler air, it condenses to form clouds. Thus, the steam consists of dry saturated steam and water particles in suspension. Similarly, In this process there is no change in elevation soz, , so the potential energy term is zero. So you stand there at the tradeshow and watch this wonderful, glass-piped WebWhen steam condenses, its volume is dramatically reduced, which results in a localised reduction in pressure. Temperature of the ordinary air measured by the thermometer when it is covered by wet cloth or wick is called as the wet bulb temperature, commonly referred to as WBT. By First Law of Thermodynamics as applied to non-flow process, heat supplied = change in internal energy + external work done. This curve is known as the dry steam line, and its horizontal distance from the vertical ordinate represents the total entropy of steam at any pressure. /Widths 12 0 R Power Plant: What Are They?

In the event that steam exists totally as vapours at saturation temperature, it is called superheated steam or superheated vapour, or dry steam. geothermal energy, form of energy conversion in which heat energy from within Earth is captured and harnessed for cooking, bathing, space heating, electrical power generation, and other uses. The external work done during this stage = P (vg vf). The value of mean specific heat of superheated steam Cp depends upon the degree of superheat and the pressure of steam generation. From dry saturated condition a vapour receives superheat and its temperature rises above saturation temperature tsat. d) none of the mentioned The exam is scheduled to be held in October 2023.
