Solve electrical network problems

Require a logic circuit designing for the attached solution, as much help as possible please as i am lost. The problem does not specify, what valves are a hazardous system, it is a closed system that serves no purpose as far as i can see. I have not studied any thermofluid systems as yet, it seems too much of a jump in kno ...continues
