BonsoirJ'ai une question:
Voila la donnée:
A manufacturer blends lubricating oil by mixing 300 kg/min of No. 10 oil with 100 kg/min of No. 40 oil in a tank. The oil is well mixed and is withdrawn at the rate of 380 kg/min. Assume the tank contains no oil at the start of the blending process. How much oil remains in the tank after 1 hr?
Puis-je considerer que le système est a l'equilibre?(Steady State) et parsuite je peux utiliser le bilan de l'accumulation, sachant qu'il n'ya pas de réactions chimiques alors:
Acc = Entr - Sort = 0 ?
Merci d'avance![]()
