"WebThe Venturi Effect. Venturi tubes are available in sizes up to 72", and can pass 25 to 50% more flow than an orifice with the same pressure drop. Furthermore, the total unrecovered head loss rarely exceeds 10% of measured d/p (Figure 2-6). The initial cost of a venturi meter is high, so they are primarily used on larger flows or on more ...
