Two open storage tanks contain different liquids. A pressure sensor in liquid R is 1.6 m below the surface. The density of liquid R is 1275 kg/m3.
A second pressure sensor is in liquid S. The density of liquid S is 850 kg/m3.
The pressure caused by the liquid above each sensor is the same.
Gravitational field strength, g=9.8 N/kgg = 9.8\ \text{N/kg}g=9.8 N/kg.
Calculate the depth of the pressure sensor in liquid S.
