A storage tank contains liquid fertiliser of density 1200 kg/m3. Two pressure sensors, P and Q, are fixed inside the tank. Sensor P is at a vertical depth of 0.35 m below the surface of the liquid. The pressure due to the liquid at sensor Q is 17 640 Pa17\,640\ \text{Pa}17640 Pa greater than at sensor P.
gravitational field strength, g=9.8 N/kgg = 9.8\ \text{N/kg}g=9.8 N/kg
Calculate the vertical depth of sensor Q below the surface of the liquid.
