example.

~Internal Energy, u~

•isothermal

•isometric 

•isobaric            =    u=Q-W

•polytropic 

•adiabatic

~Enthalpy, H~

 =u+pv

u: internal energy 

p: pressure 

v: volume 

~Continuity Equation~

~Formula~

g: gravity 

Z: height 

p: pressure 

v: volume 

C: velocity 

m: mass flowrate
