Head loss in venturi meter formula
WebAdvantages of Venturi Meter or Venturi Tube or Venturi Effects. The advantages of Venturi Meter or venturi tube or venturi effects are: No moving parts & simple operation; Long term reliability; Low head loss, as well as energy loss. Tolerance of high solids content; In a high flow rate, it is widely used. Pressure recovery is high, around 90%. WebThe pressure recovery is limited for an orifice plate and the permanent pressure loss depends primarily on the area ratio. For an area ratio of 0.5 the head loss is about 70 - 75% of the orifice differential.. The orifice …
