Pressure Formula

Pressure is the force applied by one object on the another. It is symbolized by P.
The pressure is articulated as force per unit area articulated as

Pressure formula1

Where,
F = Force applied by the body(N)
A = Total area of the object (m2)

Hydrostatic Pressure Formula can also be given by

Pressure formula 2

Where,
the height is h,
density is ρ,
gravity is g

Pressure Formula is made use of to compute pressure, force, area, density, height and gravity if some of these numerics are provided. The unit of pressure is Pascal (Pa).

Pressure Solved Examples
Underneath are problems based on pressure which may be helpful for you.

Problem 1: A 60 Kg girl wearing high heel shoes stabilizes herself on a single heel. The heel is rounded with a diameter of 1.5 cm. Calculate the pressure applied by the heel on the horizontal floor?
Answer:

Given:

Mass, m=60Kg

 

Pressure formula 3

Pressure formula 4

Force and Area

Pressure Formula 5

Pressure Formula 6

Pressure Formula 7

Problem 2: A tank is filled with water is of height 1 m. Compute the pressure exerted on the bottom of the tank.
(Acceleration due to Gravity = 9.8 m/s2, Density of water = 1000 kg / m3).
Answer:

Known:

Acceleration due to Gravity = 9.8 m/s2
Density of water = 1000 kg / m3,
The pressure is articulated as

P = ρ × g × h

P = 1000 × 9.8 × 1m
P = 9800 Pascal.
