    7. IN ORDER TO DETERMINE THE TOTAL FORCE EXERTED ON A SURFACE WE NEED TO KNOW THE PRESSURE OR FORCE PER UNIT AREA. PRESSURE = FORCE FORCE IN ? KILOGRAMS ( Kg ) AREA AREA IN ? SQ. CM ( Cm2 ) PRESSURE IN ? KILOGRAM / SQ.CM (Kg / Cm2 ) P = F A FORCE = PRESSURE x AREA THE ATMOSPHERIC AIR EXERTS UNIFORM PRESSURE ALL ROUND. THIS PRESSURE IS APPROX. 1 Kg / Cm2 AND IS DENOTED AS 1 BAR ( BAROMETER ) PRESSURE

    8. PASCAL’S LAW PRESSURE APPLIED ON A CONFINED FLUID IS TRANSMITTED ? UNDIMINISHED ? IN ALL DIRECTIONS ? ACTS WITH EQUAL FORCE ON EQUAL AREAS AND ? AT RIGHT ANGLES TO THEM FRENCH SCIENTIST PASCAL DISCOVERED THIS LAW IN THE 17th CENTURY.
