This keyword administers the distribution of lift between the pumping performed in the same pipe in both supply and return side and located in the same end of the pipe. The total lift must be determined by a boundary condition, pressure in the supply / return pipe or pressure differential in a node in the model where the pumping has authority. The keyword is placed after the key words * PIPE in the calculation file.
FORMAT:
*PQTA ”pipeid” Quota /
Pipeid: Pipe identification
Quota: Proportion in % (integer) of the total lift taken by the supply
pump. The rest, (100 – Quota) is taken by the return pump.
Quota must be in the range of 1-99.
Example:
*PQTA ”F4-F5” 50 /
*PQTA ”F7-F8” 70 /
