  1. First Law of Thermodynamics • Closed system: Q – W = (m/2)(V22 – V12) + mg(z2 – z1 ) + m(u2 - u1) • Open system: steady state, single stream: shift to (h2 – h1)

  2. Ideal Gas Law • Definition • Pure substance

  3. Compressibility • p = ZRT

  4. Compressibility • Generalized chart

  5. Ideal Gas Processes • p/T relationships • Polytropic processes: exponent • Reversible process

  6. Specific heat • Energy to raise temperature of unit mass one degree • C = Q/ (mT)

  7. Specific heat • Gas has two values • Cv – constant volume process • Cp – constant pressure process • Internal energy as f(T) • Enthalpy as f(T) • k • R
