1. A water purification plant uses one tank for chemical sterilization and a second larger tank for settling and aeration. Each tank is equipped with two sensors that measure the height of water and the flow rate respectively. When the height of water or flow rate is too high the sensors produce a logic high output. Design a logic circuit that sounds an alarm whenever the height of water in both tanks is too high and either of the flow rates is too high, or whenever both flow rates are too high and the height of water in either tank is also too high.
