A) 8.1 kW
B) 10.2 kW
C) 12.3 kW
D) 7.0 kW
Correct Answer: A
Solution :
Power generated by the turbine is, \[{{P}_{generated}}={{P}_{input}}\times \frac{90}{100}\] \[=\frac{Mgh}{t}\times \frac{90}{100}\]Putting the given values \[\frac{M}{t}=15kg/s,g=10m/{{s}^{2}},h=60m\] \[{{P}_{generated}}=(15\times 10\times 60)\times \frac{90}{100}\] \[=8.1kW\]You need to login to perform this action.
