Area of Orifice given Area at Section 2 or at Vena Contracta Solution

STEP 0: Pre-Calculation Summary
Formula Used
Area of Orifice = Cross Section Area 2/Coefficient of Contraction
ao = Af/Cc
This formula uses 3 Variables
Variables Used
Area of Orifice - (Measured in Square Meter) - Area of Orifice is the any opening, mouth, hole or vent, as in a pipe, a plate, or a body.
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.
Coefficient of Contraction - The coefficient of Contraction is ratio between the area of the jet at the vena contract and the area of the orifice.
STEP 1: Convert Input(s) to Base Unit
Cross Section Area 2: 1.8 Square Meter --> 1.8 Square Meter No Conversion Required
Coefficient of Contraction: 0.611 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ao = Af/Cc --> 1.8/0.611
Evaluating ... ...
ao = 2.94599018003273
STEP 3: Convert Result to Output's Unit
2.94599018003273 Square Meter --> No Conversion Required
FINAL ANSWER
2.94599018003273 2.94599 Square Meter <-- Area of Orifice
(Calculation completed in 00.004 seconds)
