Calculations<br />
Rectangular Flume<br />
ABSOLUTE<br />
If the flow calculation is to be absolute P702 = 1 the flow will be calculated<br />
using the formula: q = (2/3) 1.5 gn 0.5 C s C v C d bh 1.5<br />
Where:<br />
q = flowrate<br />
gn = gravitational acceleration (nominal value = 980.66 cm/s 2 )<br />
C s = shape coefficient (value = 1)<br />
C v = velocity coefficient calculated by <strong>FlowCERT</strong> LITE P721<br />
C d = discharge coeffecient calculated by <strong>FlowCERT</strong> LITE P722<br />
b = throat width P711<br />
h = head<br />
RATIOMETRIC<br />
If the flow calculation is to be ratiometric P702 = 2 the flow will be<br />
calculated using the formula: q= q cal (C v /C vcal )(C d /C dcal )(h/h cal ) 1.5<br />
Where: q = flowrate<br />
q cal = flowrate at maximum head P705<br />
C v = velocity coefficient calculated by <strong>FlowCERT</strong> LITE<br />
C vcal = velocity coefficient at maximum head<br />
C d = discharge coeffecient calculated by <strong>FlowCERT</strong> LITE<br />
P722<br />
C dcal = discharge coefficient at maximum head<br />
h = head<br />
= maximum head P704<br />
