derivation of compressibility factor vs. reduced pressure
I am supposed to derive the graph by solving equations
Homework Equations
Van der Waals equation of state
compressibility factor, Z = (Pv)/(RT)
reduced pressure = P/critical pressure
Z = f(Tr, Pr)

I need to derive the following relation:
\alpha_{S}=\alpha_{P}\frac{1}{1-\frac{\kappa_{T}}{\kappa_{S}}}
Homework Equations
Hopefully you can see that my notation |P means at constant pressure, I could not find a better way to do this, any ideas...
can anyone help me to have simple definition for compressibility and oil compressibility and why water compressibility is neglicable and for synthetic oils what is the effect of compressibilit on them compared to wter and diesel
Could anybody provide information on the bulk modulus of oil (say API Gravity 30-40) in the range of pressure 0-3000 psi and in the range of temperature 10-20 degrees C?
Many thanks

Hi there, I'd like to know if, under the conditions of thermal flows (viscous, conductive) and low Mach numbers (< 0.3), it is formally/conceptually correct to affirm that "non-divergence is only necessary condition for incompressibility"
Thank you very much in advance

Here is my problem:
A cylinder with 0.4m radius and 0.5m depth is filled with air at 20C and 1atm.
A 20.0 kg piston is lowered into the cylinder, compressing the air inside. Finally a 75 kg man stands on the piston further compressing the air which remains at 20C.
how far down does the...
Hello everyone !
I'm currently working on a problem in Eugene Hecht's Physics book. It's about static fluid and the "compressibility module". I'm not sure this traduction makes sense, because my book is translated into French and I can't find the correct English expression. For those who have...
I need equations for Isothermal compressibility & Volume expansitivity in terms of temperature and pressure. Please help. It is for refrigerants in both liquid but especially gaseous phase.
