What is the gauge pressure at the bottom of the container?

Question

A large container contains 0.250 m layer of alcohol above 0.500 m of water. What is the gauge pressure at the boundary between the alcohol and water? What is the gauge pressure at the bottom of the container? Use 8.06 X 102 kg/m3 as the density of alcohol, and 1000 kg/m3 as the density of wate

Answer 1

Since fluid pressure is ρgh

Gauge pressure at the bottom of the alcohol layer is 8.06x10³•9.81•0.25 pascals

For the pressure at the bottom of the water layer add above value to 1000•9.81•0.5
