Concept of effect:
The venturi vessel is simply implemented in the various procedures to obtain the increased value of velocity,v by constriction of the vessel's diameter or the total area required for the flow of liquids inside the vessel.And the decrease due to the constriction of the vessels area required for the flow of liquids.
But, we are provided we the given data in order to find the resultant value for the pressure,P inside the vessel.
<u>Given data:</u>
V=90 m/sec(the velocity,v at the inlet),
At=0.005,
V=90 m/sec,
∫∞=1.23 kg/m³,
V₁=√(P₁-P₂)/∫infinity[(area,A₁/final year,A)⁻¹],
Pressure,ΔP=1913.31 N/m².
