Problem 1 The system in figure below is open to 1 atm on the right side. (a) If L = 120 cm, what is the air pressure in container A? (b) Conversely, if PA = 135 kPa, what is the length L? (specific weight for water and mercury are 9790 N/m³, and 133100 N/m³ respectively) 15 cm A Air C 32 cm 18 cm Mercury L Ꭰ 35° z= 0 Water
