Question

A 80-cm-thick layer of oll floats on a 190−cm-thick layer of water. What is the pressure at the bottom of the water layer? Express your answer with the appropriate units.

Answer 1

To find the total pressure at the bottom of the water layer, we simply add the pressure exerted by both the oil and water layers: Total_pressure = Pressure_oil + Pressure_water Total_pressure = 6684.6 Pa + 11772 Pa Total_pressure = 18456.6 Pa So the pressure at the bottom of the water layer is approximately 18,456.6 Pascals.
