A piston above a liquid in a closed container has an area of 1m2. The piston carries a load of 350 kg. 3.43 kPa will be the external pressure on the upper surface of the liquid. Solution: The weight of the load is (mass) x (gravity) = (350 kg) x (9.8 m/s²) = 3,430 newtons. (3,430 newtons) / (1 m²) = 3,430 pascals = 3.43 kPa.
