A pump motor is used to deliver water at a certain rate from a given pipe. To obtain 'n' times water from the same pipe in the same time by what amount (a) the force and (b) power of the motor should be increased ?

A pump motor is used to deliver water at a certain rete from a given pipe. To obtain n times water from the same pipe in the same time, by what amount the power of the motor should be increased?

A motor of power P_(0) is used to deliver water at a certain rate through a given horizontal pipe. To increase the rate of flow of water through the same pipe 'n' times, the power of the motor is increased to P_(1) . The ratio of P_(1) to P_(0) is

.A motor of power P_(0) is used to deliver water at a certain rate through a given,horizontal pipe.To increase the rate of flow of water through the same pipe "n" times,the power of the motor is increased to P_(1) .The ratio of P 1 to P 0 is

A pipe of diameter d can drain a certain water tank in 40 minutes. The time taken by a pipe of diameter 2d for doing the same job in :

A motor is to be used to lift water from a depth of 10 m & discharging it on ground level at a speed 10m//s if 2 kg of water is lifted per second & the efficiency of motor is 40% The minimum power of the motor should be nearly :

A pump of power P ejects M kg water per second through a horizontal pipe. If power of the pump is doubled, then using the same pipe, amount of water ejected in one second will be
