This formula uses 1 Constants, 1 Functions, 4 Variables
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
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.
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).
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.
Venturi Head - (Measured in Meter) - The Venturi head refers to the difference between pressure head at inlet and pressure head at the throat.
STEP 1: Convert Input(s) to Base Unit
Cross Section Area 1: 7.1 Square Meter --> 7.1 Square Meter No Conversion Required
Theoretical Discharge: 1.277 Cubic Meter per Second --> 1.277 Cubic Meter per Second No Conversion Required
Venturi Head: 24 Millimeter --> 0.024 Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Af = sqrt((Ai*Qth)^2/((Ai^2*2*[g]*hventuri)+Qth^2)) --> sqrt((7.1*1.277)^2/((7.1^2*2*[g]*0.024)+1.277^2))
Evaluating ... ...
Af = 1.80043450809868
STEP 3: Convert Result to Output's Unit
1.80043450809868 Square Meter --> No Conversion Required
FINAL ANSWER
1.80043450809868 1.800435 Square Meter <-- Cross Section Area 2

What is Conservation of Energy?

Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. When the pendulum swings back down, the potential energy is converted back into kinetic energy. At all times, the sum of potential and kinetic energy is constant.
