New method of determination of (k1)‎ and (lo)‎ parameters of bod curve

الملخص EN

The present study presents new procedure to determine K1 and Lo parameter based on principles of calculus.

It was derived two analytical equations.

The first equation determines the parameter of K1 by knowing any two slops of tangents of the (BOD exerted versus time) curve at any two times.

While the second equation determines the parameter L0 in terms of any two slopes of tangents of the (BOD exerted versus time) curve at any two times, with substituting the parameter, K1.

A comparison is made between the results of the present procedure and those results obtained by the well-known methods of determining the parameters of K1 and Lo.

The results of comparison show good agreement with some of these methods.
