WebA flow nozzle is an engineered primary flow element for non-viscous and erosive fluids under high velocity and pressure, which would wear or damage orifice plates. Flow … 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. WebAmong these, the venturi meter is one of the oldest industrial methods of measuring flow, although other methods may be more common. Chapter 8 deals with other devices such as variable area meters, target meters, averaging pitot tubes, Dall meters, and other venturi, nozzle, and orifice-like devices. highland community residential services
