How can I get the pressure value inside a solar absorber

AI Thread Summary
To determine the pressure of water inside a solar absorber at 350°C, the vapor pressure of water at that temperature is 2350 psig. This value can be found using thermodynamic tables, making it a straightforward calculation rather than requiring direct measurement. Understanding the relationship between temperature and pressure in thermodynamics simplifies the process. The discussion emphasizes the importance of using reliable data sources for accurate calculations. Accurate pressure values are crucial for effective solar thermal energy project planning.

so I'm doing a little project in solar thermal energy and I want to do the calculations before I start anything. I am stuck on getting the value of the pressure of the water inside the absorber when the temreture gets to 350 C. Is there a way to calculate it using thermodynamics table or something less complicated or is it only obtained by direct measuring?

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
