Hi,
Below are activities to be done in sequence
1. Completely fill tank 1
2. Hold material in tank 1 for 2 hrs
3. Start filling tank 2 when tank 1 is full
4. Hold material in tank 2 for 2 hrs
5. Discharge tank 1 completely first and then only start discharging tank 2
6. Similarly when tank 2 is completely empty then only start discharge from tank 1
