A piston above a liquid in a closed container has an area of 1m2. The piston carries a load of 350 kg. What will be the external pressure on the upper surface of the liquid? A. 4.90 kPa B. 68.6 kPa C. 27.3 kPa D. 3.43 kPa
Weegy: 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 The pressure on the surface of the liquid is  (force) / (area)  =  (3,430 newtons) / (1 m²) =  3,430 pascals = 3.43 kPa. ] (More)
