Unit-2                                                                                                  PRESSURE                                                       

Ø Pressure is defined as the force acting normally over the surface of unit area.

Ø Pressure (P) =  Force / Area

Ø SI unit is Nm^-2 ( Newton per meter square ) or Pascal ( Pa)

1 Pascal is defined as the pressure exerted by one Newton force acting normally over one meter square area .i.e. 1 Pa = 1N/1m²
