The reversible work per mol done, Wrev, to expand a fuid from a molar volume
V1 to a molar volume V2 is given by
Where P the the pressure of the fluid at a volume V.
Calculate Wrev when a)
- - i.e. an ideal gas. Assume that the temperature, T, is constant
(i.e. an isothermal expansion). b)
are constants. Adiabatic expansion of an ideal gas. For information's sake
where where Cp and Cv are the heat capacities at constant pressure and volume respectively. c)
- van der Waals equation of state with a and b constants,
assume that the temperature T is constant.
