WebThe Venturi effect describes how the rate of fluid flow in an enclosed system changes as the flow enters a constricted channel. This change in fluid flow rate through a channel … WebObviously, the venturi tee has more turbulence than the monofloral one. The fluid is pressurized to flow through a smaller area. As a result, the fluid particles collide more with each other. Ultimately, there is a high chance of the fluid flow getting more disturbed. Whereas in the monoflo tee, there is also turbulence.

The diverging section of the venturi meter recovers the pressure lost in the convergent section. As a result, typical pressure losses measure around 10%. Pressure losses in an orifice meter are much greater than in a venturi meter. This is due to the lack of a pressure recovery element. cth 191
