Head of Liquid above Centre of Orifice Solution

STEP 0: Pre-Calculation Summary

Formula Used

Head of the Liquid = (Theoretical Velocity^2)/(2*9.81)
H = (V_th^2)/(2*9.81)
This formula uses 2 Variables

Variables Used

Head of the Liquid - (Measured in Meter) - The Head of the liquid is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column from the base of its container.
Theoretical Velocity - (Measured in Meter per Second) - Theoretical velocity is defined as the velocity that is calculated theoretically.

STEP 1: Convert Input(s) to Base Unit

Theoretical Velocity: 9 Meter per Second --> 9 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H = (V_th^2)/(2*9.81) --> (9^2)/(2*9.81)

Evaluating ... ...

H = 4.12844036697248

Absolute pressure head at constant head and atmospheric pressure head

Go Absolute Pressure Head = Atmospheric Pressure Head+Constant Head-(((Velocity of Liquid Outlet/0.62)^2)*(1/(2*9.81)))

Atmospheric pressure head at constant head and absolute pressure head

Go Atmospheric Pressure Head = Absolute Pressure Head-Constant Head+(((Velocity of Liquid Outlet/0.62)^2)*(1/(2*9.81)))

Loss of head due to sudden enlargement

Go Loss of Head = ((Velocity of Liquid Inlet-Velocity of Liquid Outlet)^2)/(2*9.81)

Head of liquid for head loss and coefficient of velocity

Go Head of the Liquid = Head Loss/(1-(Coefficient of Velocity^2))

Loss of head due to fluid resistance

Go Head Loss = Head of the Liquid*(1-(Coefficient of Velocity^2))

Head of Liquid above Centre of Orifice

Go Head of the Liquid = (Theoretical Velocity^2)/(2*9.81)

Head of Liquid above Centre of Orifice Formula

Head of the Liquid = (Theoretical Velocity^2)/(2*9.81)
H = (V_th^2)/(2*9.81)

What is the use of Bernoulli's equation here?

The orifice, nozzle and venturi flow rate meters use the Bernoulli Equation to calculate fluid flow rate using pressure difference through obstructions in the flow.

What happens after the vena-contracta section?

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). Beyond this section, the jet diverges and is attracted in the downward direction by gravity.
