A cylindrical hydraulic chamber is filled with synthetic oil. The oil exerts a force of 13.5 kN13.5\text{ kN}13.5 kN on the face of the piston at the bottom of the chamber. The cross-sectional area of this piston face is 0.018 m20.018\text{ m}^20.018 m2.
Calculate the pressure exerted by the oil on the piston face.
Use the equation:
pressure=forcearea \text{pressure} = \frac{\text{force}}{\text{area}} pressure=areaforceState the unit of your answer. Choose the unit from: kg/m3\text{kg/m}^3kg/m3, N/m\text{N/m}N/m, Pa\text{Pa}Pa.
