• # question_answer Consider the following data for the performance of a centrifugal pump: Speed: 1200 rpm, flow rate 30 $l/s,$ head 5 k W If the speed is increased to 1500 rpm, the power will be nearly equal to: A) 6.5 kW             B) 8.7 kWC) 9.8 kW             D) 10.9 kW

$P\alpha {{N}^{3}}.{{P}_{2}}={{P}_{1}}{{\left( \frac{{{N}_{2}}}{{{N}_{1}}} \right)}^{3}}=5{{\left( \frac{1500}{1200} \right)}^{3}}$ = 9.8 kW
