<!-- EDIT BELOW THIS LINE TOPIC:CONTINUITY EQUATION:→ this equation is based on the conservation of mass. it states that that the mass rate flow (haw much mass is flowing per unit time through a section ) of fluid through a pipe or channel at any point in the fluid is constant. consider two sections 1-1 and 2-2 in the fluid. let A1 ,ρ1 ,v1 be the area,density,velocity respectively at section 1-1. and A2,ρ2,v2 be corresponding values for section 2-2. so mass rate flow at section 1-1 = mass of flowing fluid at section 1-1 ÷avg.time =density ×volume÷time =ρ1×A1×v1 similiarly for sectoin 2-2; mass rate of flow =ρ2×A2×v2 so continuity equation is ; ρ1×A1×v1 =ρ2×A2×v2

if fluid is imcompressible ( means density remains same throught the flow) ,then ρ1=ρ2 so continuity eqn reduces to ; A1×v1=A2×v2
