Question

Derive the expression for pressure.

Answer 1

Pressure can be defined as the force acting per unit area. So ,mathematically we can write-
Pressure (P)=Force (F)/Area (a)
=Thrust (T)/Area (a)

Answer 2

Answer:

P=F(thrust)/A

Explanation:

Pressure is force acting per unit area

SO,

P=Pressure

F=Force or thrust

A=Area on which force acts

It can also be expressed as

1 Pa= 1 N/1 m/s^2
