• question_answer A centrifugal pump delivers water at the rate of 50 litres/s against a total head of 40 metres. Then the Power required to drive the pump is: A) 2 k W               B) 15.2 k WC) 19.6 k W                      D) 25.8 k W

Solution :

$Q=50\times {{10}^{-3}}\,{{m}^{3}}/s,$ H=40 m $Q=50\times {{10}^{-\,3}}\,{{m}^{-\,3}}/s,$ H=40 m $P=\frac{\gamma QH}{{{10}^{3}}}=\frac{9-81\times {{10}^{3}}\times 50\times {{10}^{-3}}\times 40}{{{10}^{3}}}$             = 19.62 km
