Pressure Loss Coefficient at Inlet of Duct Solution

STEP 0: Pre-Calculation Summary
Formula Used
Pressure Loss Coefficient at 1 = (1-Cross-Sectional Area of Duct at Section 1/Cross-Sectional Area of Duct at Section 2)^2
C1 = (1-A1/A2)^2
This formula uses 3 Variables
Variables Used
Pressure Loss Coefficient at 1 - Pressure Loss Coefficient at 1 is the coefficient of pressure losses caused by a change in air direction from the elbow, offset, or takeoffs.
Cross-Sectional Area of Duct at Section 1 - (Measured in Square Meter) - The Cross-Sectional Area of Duct at Section 1 is defined as the area of the section at point 1.
Cross-Sectional Area of Duct at Section 2 - (Measured in Square Meter) - The Cross-Sectional Area of Duct at Section 2 is the area of the cross-section at section 2.
STEP 1: Convert Input(s) to Base Unit
Cross-Sectional Area of Duct at Section 1: 1.452941 Square Meter --> 1.452941 Square Meter No Conversion Required
Cross-Sectional Area of Duct at Section 2: 0.95 Square Meter --> 0.95 Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
C1 = (1-A1/A2)^2 --> (1-1.452941/0.95)^2
Evaluating ... ...
C1 = 0.280276619923546
STEP 3: Convert Result to Output's Unit
0.280276619923546 --> No Conversion Required
FINAL ANSWER
0.280276619923546 0.280277 <-- Pressure Loss Coefficient at 1
