Pertimbangkan dua tangki larutan air garam yang saling bersambung. Kapasiti setiap tangki adalah 360 liter. Air tawar dituang ke dalam tangki A pada kadar 5 liter/min. Terdapat dua paip yang menyambungkan tangki A ke tangki B. Paip pertama mengepam larutan garam dari tangki B ke dalam tangki A pada kadar 4 liter/min. Paip kedua mengepam larutan garam dari tangki A ke dalam tangki B pada kadar 9 liter/min. Akhir sekali, terdapat saliran pada tangki B yang mana larutan garam mengalir pada kadar 5 liter/min. Oleh itu, setiap tangki mengekalkan isi padu tetap 360 liter larutan garam. Pada mulanya, terdapat 60 kg garam dalam tangki A, tetapi tangki B mengandungi air tulen. Consider two interconnected tanks of brine solution. The capacity of each tank is 360 litres. Fresh water is poured into tank A at a rate of 5 litres/min. There are two pipes connecting tank A to tank B. The first pumps salt solution from tank B into tank A at a rate of 4 litres/min. The second pumps salt solution from tank A into tank B at a rate of 9 litres/min. Finally, there is a drain on tank B from which salt solution drains at a rate of 5 litres/min. Thus, each tank maintains a constant volume of 360 litres of salt solution. Initially, there are 60 kg of salt present in tank A, but tank B contains pure water.
