Auswertung der Gasdruckmessung

§ 27. Die Auswertung der Messergebnisse erfolgt nach den Regeln der Statistik nach folgenden Formeln:

 

                 -          1     n

 

                 P tief n = - . Sigma P tief i

 

                            n     1

 

                                       n (-                  )2

 

               S tief n = Wurzel Sigma   (P tief n - P tief i)

 

                                       l (                   )

 

                                 ------------------------------

 

                                          n - 1

 

Es bedeutet: P tief i:   den Gasdruck der einzelnen Messung;

 

             n:          die Anzahl der Messungen;

 

             P tief max: den maximal zulässigen mittleren Gasdruck;

 

             -

 

             P tief n:   den arithmetischen Mittelwert des

 

                         Gasdruckes aus n Messungen;

 

             S tief n:   die Standardabweichung des Gasdruckes aus

 

                         n Messungen;

 

             K tief in:  den Toleranzkoeffizient bei n Messungen

 

                         gemäß folgender Tabelle, um eine statische

 

                         Sicherheit zu erhalten bei:

 

                         K tief 1n 99% der Fälle;

 

                         K tief 2n 95% der Fälle;

 

                         K tief 3n 90% der Fälle.
