Constants Used
[g] - Gravitational acceleration on Earth Value Taken As 9.80665
Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Venturi Head - (Measured in Meter) - The Venturi head refers to the difference between pressure head at inlet and pressure head at the throat.
Theoretical Discharge - (Measured in Cubic Meter per Second) - The Theoretical Discharge refers to the ideal flow rate of a fluid through a system, calculated under perfect conditions without considering any real-world losses like friction or turbulence.
Cross Section Area 1 - (Measured in Square Meter) - The Cross Section Area 1 refers to the area of cross section at the inlet of the structure (venturi meter or pipe).
Cross Section Area 2 - (Measured in Square Meter) - The Cross Section Area 2 refers to the area of cross-section at the throat (venturi meter) of the structure.
STEP 1: Convert Input(s) to Base Unit
Theoretical Discharge: 1.277 Cubic Meter per Second --> 1.277 Cubic Meter per Second No Conversion Required
Cross Section Area 1: 7.1 Square Meter --> 7.1 Square Meter No Conversion Required
Cross Section Area 2: 1.8 Square Meter --> 1.8 Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
hventuri = ((Qth/(Ai*Af))*(sqrt(((Ai)^2-(Af)^2)/(2*[g]))))^2 --> ((1.277/(7.1*1.8))*(sqrt(((7.1)^2-(1.8)^2)/(2*[g]))))^2
Evaluating ... ...

What is Venturi Head?

A Venturi meter is used to measure the flow rate through a tube. It is based on the use of the Venturi effect, the reduction of fluid pressure that results when a fluid runs through a constricted section of pipe. It is called after Giovanni Battista Venturi (1746-1822), an Italian physicist.
