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. Web22 de may. de 2024 · As was written, the most common configuration, known as pool boiling is when a pool of liquid is heated from below through a horizontal surface. In pool boiling the liquid is quiescent and its motion near the surface is primarily due to natural convection and to mixing induced by bubble growth and detachment. The pioneering work on boiling was ...
