A tank shown in Figure has the following Boolean variables: flow rates, QA, QB, and QC; pressure, P; and level, L. All are high if the variable is high and low otherwise. Devise Boolean equations for two alarm conditions as follows:

a. OV = overfill alarm

1. If either input flow rate is high while the output flow rate is low, the pressure is low and the level is high.

2. [If both input flow rates are high while the output flow rate is low and the pressure is low.]

b. EP = empty alarm

1. If both input flow rates are low, the level is low and the output flow rate is high.

2. If either input flow rate is low, the output flow rate is high and the pressure is high.
