High School Reading properties from a steam table

Click For Summary
The steam table in question provides specific volume for vapor (Vg) but lacks the specific volume for liquid (Vf) at 0.1 bar. Users are advised to consult alternative tables, such as those by Cengel, which typically include Vf. The discussion highlights the importance of understanding the relationship between internal energy (u), enthalpy (h), and pressure (p) for calculating specific volume. A formula is provided for calculating specific volume based on these parameters. Accurate data on Vf is crucial for thermodynamic calculations.

Hello!
I see this Steam table:

It shows Vg but not Vf. It mentions some equations at the bottom. Does anyone know how much is Vf for 0.1bar?

you could widen the question: does anyone know what You mean with Vf? ?

if you want the specific volume of the liquid, find another table that shows it...e.g. cengel

I would expect a table such as this to list vf. However since u = h - pv, then
v by calculation is: v = (h - u)/p.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
