Question

a motor pump lifts water from an average dept of 15m at the rate of
5kg per second if the water is coming out of the pump with a
velocity of 4ms-1, the power of the motor is? ( g=
10ms-1) (ans : 790W)

Let the power of the engine is P,Therefore           P=mt×g×h  + 12mv2=5×10×15   + 12×5×4×4or                      P=750  +  40 = 790W

a motor pump lifts water from an average dept of 15m at the rate of 5kg per second. if the water is coming out of the pump with a velocity of 4ms-1, the power of the motor is? ( g= 10ms-1) (ans : 790W)

a motor pump lifts water from an average dept of 15m at the rate of 5kg per second. if the water is coming out of the pump with a velocity of 4ms^-1, the power of the motor is? ( g= 10ms^-1) (ans : 790W)
