Question

show that liquid pressure p=hdg where h is depth of liquid d is density of liquid and g is gravity

Answer 1

The volume of the liquid=Ah
Suppose the density of the liquid is d
Then the mass of the liquid =Ahd
The force exerted by the liquid=Ahdg
The pressure exerted by the liquid =force÷area= Ahdg÷A =hdg
Pressure =hdg
