∇ Choice of Flow unit:
( l/h …tot … m3/s );
∇ Scale (graphics on PC only):
Outputs: see menu « General »
∇ Product (+ / -) :
- If WATER: C = 1300 to 1600 m/s
- If OTHER:
∇ Fluid Characteristic
and speed of sound range :
∇ Hydraulic corrections (+ / -)
Prefer mode AUTO.
∇ Entry of Coefficient KH or data to do
its calculation :
- If MANUAL: entry of coefficient
depending on profile : Laminar = 1.333
or Turbulent = 1.03 to 1.08
- If AUTO: entry of parameters:
∇ Fluid viscosity:
∇ Pipe roughness:
As well as the critical Turbulent /
Laminar flow transition:
∇ Critical Reynolds Number (ReyC)
∇ Transition range (LBR):
