[TRNSYS-users] Doubt component Type 749

[David BRADLEY]

Sergio,
   The first line of the data file contains values of normalized pump 
speed (rotational speed over rotational speed at full-speed operation). 
The second line contains values of pump flow rate (in L/s). The rest of 
the lines contain two values each. The first is the pump head [m] and 
the second is the pump efficiency [0..1] for each combination of 
normalized pump speed and pump flowrate listed in the first two lines. 
The data file should be constructed from manufacturer's data on the pump 
that you are planning to use in your simulation.
Kind regards,
  David
