Pressure—-

“pressure is the amount of force applied perpendicular to the surface of an object per unit area.”

Unit of Pressure—–

                             p=F/A

         ——————————–

           Unit—– Newton/meter^2

Pressure of Liquid—–

               Pressure of Liquid at any depth the Liquid.             

P=h•d•g

Where,

                      h= depth of liquid

                    d=volume of liquid

                  g= acceleration gravitational
