Given:
The mass of liquid contained in a cylindrical vessel of cross sectional area A is 800 kg. Pressure at the bottom of the vessel is 4 × 10⁴ Pascal.
To find:
Value of area A
Concept:
Force in this question is better termed as Thrust , Thrust is the perpendicular force acting on the bottom surface of the vessel.
Pressure is a scalar quantity denoting the distribution of Thrust over a specified surface area.
Mathematically , pressure is calculated by the ratio of the force and the the area upon which it acts.
Calculation:
So final answer is :
Area of cross-section of vessel : 0.2 m²
