Question

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?

Short answer

a) Total pressure = 106 kPa

b) P_C-P_A = 4263 Pa and P_B - P_A = 4263 Pa

Step-by-step solution

Part(a) Step1: Given information

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

Part(a) Step 2: Explanation

Calculate the pressure at point A

PA = h ρ g

= (0.5m) x (870 kg / m³) (9.8 m/s²) = 4263 Pa

P_Total = P_atm + P_oil

P_Tota = 101325+4263 Pa=106 kPa
