In thermodynamics, superheating (sometimes referred to as boiling retardation, or boiling delay) is the phenomenon in which a liquid is heated to a temperature higher than its boiling point, without boiling. This is a so-called metastable state or metastate, where boiling might occur at any time, induced by external or internal effects. Superheating is achieved by heating a homogeneous substance in a clean container, free of nucleation sites, while taking care not to disturb the liquid. WebThe refrigerant is now cooled at constant pressure until it exists as a liquid at 15 C. Determine the amount of heat loss and show the process on a T-v diagram with respect to ; Superheated water vapor at 100 kPa and 400 C is allowed to cool at a constant volume to 80 C. Draw a schematic with the problem statement, and include the T-V diagram ...

WebSep 16, 2012 · The T - V diagram is a clearer way of visualizing it. If I draw a vertical line (since V remains constant) the position 2 will fall out of the bounds of the saturated vapor and into those of superheated vapor. I also found an easier way of evaluating these things. According to a diagram I found online, If V1 < V2 f, it WebThe excess energy = 2 741.7 - 2 706.7 = 35 kJ/kg, and this is used to raise the temperature of the steam from the saturation temperature of 120 °C to 136 °C. The degree of superheat can be determined either by using superheated steam tables, or by using a Mollier chart. WebInstrumentation.
