    A motor pump-set lifts 300 kg of water per minute from a well of depth 20 m and delivers to a height of 20 m. Then its power is:

    A)  3 kW                                    

    B)  1.96 kW              

    C)         0.98 kW              

    D)         3.92 kW

    Correct Answer: B

    Solution :

    From the formula, work done by lifting water per second \[=300g\frac{\left( d+h \right)}{t}\] \[=300\times 9.8\times \frac{(20+20)}{60}\] \[1960\,W=1.96\,kW\]
