Superheated volumes checked using http://webbook.nist.gov/chemistry/fluid/[edit]

At values specified by the table[edit]

T(Celsius) = 350 ... p(bars) = 1.50E+02 bars ... (0.17% error)[edit]

  • (Superheated steam) values from the Wikiversity table:
    • v = volume (m^3/kg) = 1.15E-02
  • Wikipedia's percent error (X_wiki - X_true)/X_true:
    • error(v)= .166%

T(Celsius) = 380 ... p(bars) = 400 ... (0.11% error)[edit]

  • (Superheated steam) values from the Wikiversity table:
    • v = volume (m^3/kg) = .00168
  • "True" values from http://webbook.nist.gov/chemistry/fluid/:
    • v = volume (m^3/kg) = .0016819
  • Wikipedia's percent error (X_wiki - X_true)/X_true:
    • error(v)= 0.11%

T(Celsius) = 500 ... p(bars) = 500 (0% error)[edit]

At values midway between table specifications[edit]

T(Celsius) = 400.....P midway between 50 bars and 100[edit]

T(Celsius) = xxx .....P midway between xxx bars and xxx[edit]

T(Celsius) = xxx .....P midway between xxx bars and xxx[edit]
