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) - Cross Section Area 2 is defined as the area of cross-section at the throat (venturimeter) of the structure.
Cross Section Area 1 - (Measured in Square Meter) - Cross Section Area 1 is the area of cross section at the inlet of the structure (venturimeter or pipe).
Theoretical Discharge - (Measured in Cubic Meter per Second) - The Theoretical Discharge is given by the theoretical area and velocity.
Venturi Head - (Measured in Meter) - Venturi headt is 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))

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.
