Pd = 0.6*V2^2*C2
This formula uses 3 Variables
Variables Used
Dynamic Pressure Loss - (Measured in Pascal) - Dynamic Pressure Loss is defined as the loss of pressure is due to the loss of the energy of the fluid in overcoming such dynamic forces resisting the changes.
Velocity of Air at Section 2 - (Measured in Meter per Second) - Velocity of Air at section 2 is defined as the rate of air movement measured in distance traveled relative to time elapsed at section 2.
Pressure Loss Coefficient at 2 - Pressure Loss Coefficient at 2 is the coefficient of pressure losses caused by a change in air direction from the elbow, offset, or takeoffs.
STEP 1: Convert Input(s) to Base Unit
Velocity of Air at Section 2: 26 Meter per Second --> 26 Meter per Second No Conversion Required
Pressure Loss Coefficient at 2: 0.3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pd = 0.6*V2^2*C2 --> 0.6*26^2*0.3
Evaluating ... ...
