Let us consider a fluid is at rest and this fluid puts pressure at a point O of small area dA. If the force acted on O is dF, then pressure can be given by-
Pressure, P = dF/ dA
Or,
P = F/ A (Suppose force is acted uniformly on the area A)
Unit of Pressure:
P = N/ m2
= Pascal (Pa)
1 bar = 105 Pa or 105 N/m2
