The container shown in FIGURE EX14.12 is filled with oil. It is open to the atmosphere on

the left.a. What is the pressure at point A?b. What is the pressure difference between points A and B? Between points A and C?

a) Total pressure = 106 kPa

b) P_{C}-P_{A} = 4263 Pa and P_{B} - P_{A} = 4263 Pa

The tank and points (A, B and C) are given in figure

Calculate the pressure at point A

PA = h ρ g

= (0.5m) x (870 kg / m^{3}) (9.8 m/s^{2}) = 4263 Pa

P_{Total} = P_{atm} + P_{oil}

P_{Tota} = 101325+4263 Pa=106 kPa
