Several issues in calculating the reheater
Thread Content
Suppose an example involves heating with steam; the steam flows on the tube side at a temperature of 146°C. The fluid on the shell side is heated, resulting in a phase change – the liquid phase turns entirely into a gas phase, with a vaporization rate of around 50%. The temperature ranges from 84°C to 111°C. What are the saturated temperatures in this case? The qualitative temperature TD is 146°C, so what is tD? Due to uncertain data, I would like to ask everyone for advice! ! !

It should be 100%, right? The liquid phase has completely turned into a gas phase! There is a temperature range; is it a supercooled liquid at low temperatures? Or superheated steam at high temperatures? What is the boiling point?
Shell side, Tube side, Total flow: 1999, 268. Steam: 932, Liquid: 1067. In 1999: Water vapor: 268, Water: 268. Temperatures: 84, 111, 146, 146
The conditions aren’t sufficient; there’s not enough data on the cold side
