Area at Section 2 or at Vena Contracta Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cross Section Area 2 = Coefficient of Contraction*Area of Orifice
A_f = C_c*a_o
This formula uses 3 Variables

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.
Coefficient of Contraction - The Coefficient of Contraction refers to the ratio between the area of the jet at the vena contract and the area of the orifice.
Area of Orifice - (Measured in Square Meter) - The Area of Orifice refers to the any opening, mouth, hole or vent, as in a pipe, a plate, or a body.

STEP 1: Convert Input(s) to Base Unit

Coefficient of Contraction: 0.611 --> No Conversion Required
Area of Orifice: 4.4 Square Meter --> 4.4 Square Meter No Conversion Required

STEP 2: Evaluate Formula
