Question 1

A cylindrical column in a chemical processing plant is filled with a high-density solvent. The solvent exerts a downward force of 162 N162\text{ N}162 N on the seal at the bottom of the column. The cross-sectional area of this seal is 0.0045 m20.0045\text{ m}^20.0045 m2.

Calculate the pressure exerted by the solvent on the seal.

Use the equation:

pressure=forcearea \text{pressure} = \frac{\text{force}}{\text{area}} pressure=areaforce​

Choose the unit from: kg/m3\text{kg/m}^3kg/m3, N/m\text{N/m}N/m, Pa\text{Pa}Pa.
