A barrel contains a 0.160 m layer of oil floating on water that is 0.170 m deep. The density of the oil is 600 kg/m3.

a. What is the gauge pressure at the oil-water interface?

b. What is the gauge pressure at the bottom of the barrel?

Step 1

**Given information:**

Height of water level in the barrel (h_{w}) = 0.170 m

Height of oil level above the water-oil interface (h_{o}) = 0.160 m

Density of the oil (ρ_{o}) = 600 kg/m^{3}

Density of water (ρ_{w}) = 1000 kg/m^{3}

Step 2

Pressure at the water-oil interface (P_{i}):

Step 3

Pressure at the bottom of the w...
