5:88 þ f ¼ 2q
ð6:E13Þ
0:62 ¼ r
ð6:E14Þ
0:02 ¼ s
ð6:E15Þ
Solving above equations, the values of f, p, q, r, and s were found to be
f ¼ 4:68
p ¼ 4:35
q ¼ 5:28
r ¼ 0:62
s ¼ 0:02
Similarly, for sewage sludge
11:79 ¼ p þ q
ð6:E16Þ
12:34 þ 2f ¼ 4p þ 3r þ 2s
ð6:E17Þ
6:34 þ f ¼ 2q
ð6:E18Þ
0:87 ¼ r
ð6:E19Þ
0:03 ¼ s
ð6:E20Þ
Solving above equations, the values of f, p, q, r, and s were found to be
f ¼ 6:20
p ¼ 5:52
q ¼ 6:27
r ¼ 0:87
s ¼ 0:03
