Explanation / Answer

Pressure at A PA = oil × h + water ×h

Given h = 4.5 ft

specific weight of oil oil = 55.1  lb/ft3

specific weight of water water  = 62.4 lb/ft3

PA = (55.1+62.4) × 4.5

PA = 528.75 lb/ft2

PA = 528.75/122 1ft = 12 inch

PA = 3.671875 psi

Pressure at B PB = PA - water × (h2 +1)

PB = 528.75 - 62.4 × (3.5+1)

PB = 247.95 lb/ft2

PB = 1.721875 psi

Pressure at C PC = PA - water × (1)

PC = 528.75 - 62.4 × (1)

PC =  466.35 lb/ft2

PC = 3.238 psi
