Model equations describe mathematical relationships between different flows. In this assignment, we will look at such a connection. You have been given information that in P3 (the bottling) it is the case that " 1 of 200 boxes ends up as wastage (loss). Aluminum in this loss is sent for recycling in P5. The rest of the boxes go to consumption. Use this information to calculate x35 as a function of x23 Provide the answer as a Python code and function named "CalculateFlow 35 ". Remember to use the correct syntax to define functions, i.e. "def", "return" etc. (P1) produces aluminum sheets. In process P1,72% of aluminum entering the process (primary and recycled) is converted into aluminum sheets which are then sent to Process 2, P2. Inflow of aluminum is a mixture of primary aluminum (new aluminum) and recycled aluminum from Process 5, P5. New aluminum comes from outside the system and is therefore an "import". Losses from plate production in P1 are sent for recycling in P5. (P2) produces beverage cans. In the process P2,79% of the aluminum in aluminum sheets is converted into aluminum cans. The cans are then sent for bottling in P3. Losses from box production are sent for recycling in P5. (P3) which bottles drinks and sells drinks in cans. In the process P3, there is a wastage (loss) of 1 in every 200 cans. Losses from P3 are sent for recycling in P5, the rest is sold for consumption in P4. (P4) is the drink's consumption phase. In process P4, a proportion of 85% of the boxes are sorted for recycling in P5, while the rest goes unsorted out of the system for general waste treatment. The proportion that does not go to recycling therefore leaves the system as "export". (P5) recovers aluminum. In process P5, cans from the consumption phase (P4), aluminum plate production (P1), can production (P2), and bottling of cans (P3) are melted down into recycled aluminum. Overall, for the entire process in P5, there is a loss of 2.5% which is sent to other waste management and thus leaves the system (as export). Recycled aluminum from P5 is sent to plate production in P1
