For water properties:

Viscosity = 0.001 Pascal-seconds

Density = 1000 kg/m³

Depending upon ow type and Reynolds Number value, we use

one of the following methods for computing Pressure Loss:

1) Laminar Flow method (if Reynolds Number < 3,000)

2) Smooth Pipe method (if Reynolds Number > 3,000 and

Boundary Layer Thickness < Pipe Roughness)

3) Prandtl equation method (if Reynolds Number < 100,000

and Pipe Roughness > Boundary Layer Thickness)

4) Karman Equation method (all other conditions)
