Length Of Converging Cone Of Venturimeter
Length Of Converging Cone Of Venturimeter. The venturimeter should be proceeded by a straight pipe of not less than 5 to 10 times the pipe diameter and free from fittings, misalignment and other source of large scale turbulence. In the divergent cone fluid expands with high pressure and high velocity this due to damage the pipe line thats why to compensate this divergent cone is always 3 to 4 times the convergent cone.
The pressure difference between the upstream end if the cone and the throat is. The manometer was used to measure pressures in the pipe, expressed in terms of head So, the pressure is build up again to the original inlet pressure.
Angle Of Converging Cone Is From 14° To 20°.
Length of convergent part is greater than length of divergent part. Throat diameter (the area is constant). If divergence angle is very large, then back pressure will increase by great extent & eddies formation will take place resulting in flow separation.
Throat Part The Throat Is Placed In The Middle Of The Venturi Meter Or Venturi Tube.
Venturimeter is an instrument used to measure the discharge of liquid flowing in a pipe. The venturimeter should be proceeded by a straight pipe of not less than 5 to 10 times the pipe diameter and free from fittings, misalignment and other source of large scale turbulence. In the pipe, fluid is flowing so first it enters into a converging cone then thorat and then diverging cone.
Diameter Of The Throat Varies Between 1/3 To 3/4 Of Pipe Diameter.
So, the pressure is build up again to the original inlet pressure. The manometer was used to measure pressures in the pipe, expressed in terms of head Venturimeter consists on a short converging cone which has total included angle of 21 ± 1 o leading to a cylindrical portion of short length called throat.
What Is The Maximum Angle Of Divergence In The Venturimeter?
The convergent cone of length l tapers from the pipe diameter to the throat diameter. Converging cone or diameter (the area is decreasing). It is the middle part of the venturimeter.
Actually When The Flow Emerges From The Throat Area Of Venturi To Enter Into The Diverging Section, Their Is A Negative Pressure Gradient.
Second one is cylindrical throat. The d is the diameter of the inlet section and d is the diameter of the throat. The converging takes place normally at 21±2° angle.
