Practice Problems on Process Analysis Question 1: The diagram in Figure 1 below shows the sake (rice wine) making process. A mixture of treated rice and other materials is added to a fermentation tank. Raw materials are added at a rate of 5,000 litres per day. After 10,000 litres have been added to the tank, the tank is sealed and the mixture ferments for 30 days. After the fermentation process is completed, raw sake flows out of the tank and into the filter at a rate of 1200 litres per day. Sake continuously flows through the filter and ten days after the first sake enters the filter, sake begins to flow out of the filter, also at a rate of 1200 litres per day. As soon as the fermentation tank is empty, it undergoes a 3-day cleaning process and then begins receiving the next batch of raw materials. As soon as the filter is completely empty, it undergoes a 5-day cleaning process. What is the long-run average capacity of this system in litres per day?
