Why is water at 90℃ in HTRI still in a vapor state?
Thread Content
A mixture of air and water vapor at 150 degrees Celsius is cooled down to 90 degrees Celsius. Why is the water still in a gaseous state?
Your inlet pressure is only 70 KPa; the saturated steam pressure of water at 90°C is 0.715 kgf/cm2 = 71.5 KPa
Pressure! It is also advisable to develop a good* habit of entering the fluid name; P
The partial pressure of water vapor has not yet reached the saturation pressure
Abroad, pressure is generally measured in terms of absolute pressure. Moreover, there is gaseous water in the air at room temperature; otherwise, how could it rain?
What about pressure? Is it in a negative pressure state?
