Values are presented as means ± standard error of triplicates except for ER and BD which are means of 10 and 20 readings respectively. Values connected by the same
letter in each row are not significantly different (P<0.05).
Treatments No: 1=85 rpm SS & 232.5°CBT; 2=60 rpm SS & 232.5°CBT; 3=110 rpm SS & 275°CBT; 4=85 rpm SS & 275°CBT; 5=60 rpm SS & 190°CBT; 6=110 rpm SS &
