Answer:
P=11 kW
Explanation:
Given that
Number of poles= 8
I.E.C. 180L motor frame
From data book , for 8 poles motor at 50 Hz
Speed = 730 rpm
Power factor = 0.75
Efficiency at 100 % load= 89.3 %
Efficiency at 50 % load= 89.1 %
Output power = 11 kW
Therefore the rated output power of 8 poles motor will be 11 kW. Thus the answer will be 11 kW.
P=11 kW

Answer:
The waste flow rate is 81.05 m3/h
Explanation:
According to the given data we have the following:
Influent SS concentration (CIn): 220 mg/L
Influent flow rate (QIn) : 450 m3/h
Effluent concentration (Cout): 45 mg/L
Waste sludge concentration (Cw): 10,000 mg/L
Qout + Qw= 450 m3/h
CIn QIn=Cout Qout+ Cw Qw
220*450=45Qout + 1000Qw
45Qout+1000Qw=99,000
Therefore, Qout=398.95 m3/h
Qw=81.05 m3/h
The waste flow rate is 81.05 m3/h
Answer:
