UNIT 5 (HORIZONTAL AND INCLINED VENTURI METER)

P= pressure of section

V= velocity of section

A= area of section 

W= liquid in pipeline (specific weight,wg)

G= gravity (9.81m/s²)

Z= height above datum
Qactual = Cd A1√2gH/m²-1
Qactual = flowrate
Cd= coeficient of discharge

       

                       Bernoulli's equation

          Z1+ V1²/2g +P1/W = Z1+ V2²/2g+P2/W



                             Inclined Pipe

 Horizontal meter Z1+Z2

                      V2²-V1²/2g = P1-P2/W

                               A=πd²/4
