RATIOMETRIC
If the flow calculation is to be ratiometric P702 = 2 the flow will be
calculated using the formula: q= q
cal
C
e
/C
ecal
(h
e
/h
ecal
)
1.5
Where: q = flowrate
q
cal
= flowrate at maximum head P705
Ce = discharge coefficient calculated by Flow 3 P723
Ce
cal
= discharge coefficient at maximum head
he = effective head
he
cal
= effective head at maximum head
