Motor Energy

$$motor \ energy = \frac{\sqrt{3} \times pf \times v \times A}{1000}$$

In CAS terms:

$$ob.c2in.energyFlow.use = 3**0.5 * ob.powerFactor.use * ob.c2in.amps.use / 1000.0$$

Total Coal Flow

$$Total\ Coal\ Flow = \sum mills\_output\_fuelflow$$

In CAS terms:

$$Total\ Coal\ Flow = \sum mill.coalIn.massFlow.meas$$

Total Milling Power

$$Total\ Milling\ Power = \sum mills\_load$$

In CAS terms:

$$Total\ Milling\ Power = \sum mill.motor.c1in.energyFlow.use$$

Total PA Flow

$$Total\ PA\ Flow = PAF\_A\ outlet\ air\ flow + PAF\_B\ outlet\ air\ flow$$

In CAS terms:

$$Total\ PA\ Flow = paf\_a.c1out.massFlow.use + paf\_b.c1out.massFlow.use$$

Total SA Flow

$$Total\ SA\ Flow = FDF\_A\ outlet\ air\ flow + FDF\_B\ outlet\ air\ flow$$

In CAS terms:

$$Total\ SA\ Flow = fdf\_a.c1out.massFlow.use + fdf\_b.c1out.massFlow.use$$

Milling Power to Coal Ratio

$$milling \ power \ ratio = \frac{motor \ energy}{coalin \ massflow}$$

In CAS terms:

$$ob.millPowerCoalRatio.use = ob.totalMillPower.use / ob.totalCoalFlow.use$$

PA Flow to Coal Flow

$$PA \ Flow \ Ratio = \frac{PA \ Flow}{Coal \ Flow}$$

In CAS Terms:

$$ob.PaFlowCoalRatio.use = ob.totalPaFlow.use / ob.totalCoalFlow.use$$
