Untuk laju alir F4 = 59.349,10221 kg/ jam, olein yang dihasilkan sebesar 42.264,46 kg/jam sehingga tidak mencukupi nilai kapasitas per jam dari pabrik sebesar 42.968,75 kg/jam. Sedangkan jika laju alir F4 = 1000 kg/jam, akan menghasilkan 712,1331 kg/jam. Untuk mencukupi kapasitas per jam dari pabrik, dapat dicari dengan cara trial.

(1000 : 712,1331) x 42.968,75 = 60.338,09 kg/jam

Jadi, laju alir F4 = 60.338,09 kg/jam
