vena contracta meaning in Hindi

Examples

1. If the pressure at the vena contracta drops below the vapor pressure of the fluid bubbles will form in the flow stream.
2. Deriving the above equations used the cross-section of the orifice opening and is not as realistic as using the minimum cross-section at the vena contracta.
3. To maintain a steady flow of liquid through a valve the flow velocity must be greatest at the vena contracta or the point where the cross sectional area is the smallest.
4. There is not much head loss between cross section 1, before the contraction, and cross section 3, the vena contracta at which the main flow is contracted most.
5. A hole ( or'ori
   �ce') tone is produced by a fast-moving cylinder ( or'vena contracta') of air that interacts with the slow-moving anulus of air surrounding it.
6. He had discovered a contraction in the vein of fluid ( " vena contracta " ) which issued from the orifice, and found that, at the distance of about a diameter of the aperture, the section of the vein was contracted in the subduplicate ratio of two to one.
7. "' Vena contracta "'is the point in a fluid stream where the diameter of the stream is the least, and fluid velocity is at its maximum, such as in the case of a stream issuing out of a nozzle, ( orifice ) . ( Evangelista Torricelli, 1643 ).
