Pulsation Dampers - Add Friction From System Flow Resistance

Add Friction From System Flow Resistance to "A.H." figure. Also known as "Viscous drag" "scrubbing action" "Rotary flow" "Reynolds effect".

Pipe Fitting Component Round the corner of a Tee Past a side opening of a Tee Back into line from a side opening in a Tee Rounded corner 90° elbow (Long Rad. or L.R.90) Abrupt 90° elbow ("hard" 90 or Machined "L") Gentle 45° elbow (Bends & or "5D" 90)

Effective Length of Pipe System Leff := L+(0.0667xDxT1)+(0.0209xDxT2)+(0.0667xDxT3)+(0.0327xDxE1)+(0.0681xDxE2)+(0.0144xDxE3) Figures applied for E and T are averages from tests

2. CALCULATIONS 2.1 Velocity V of the flow in the pipe:
2.2. Reynolds Number: 2.3 Friction Factor: (cold drawn pipe)
2.4. Pressure loss:
